  • Tkinter Gui to read in csv file and generate buttons based on the entries in the first row

    - by Thomas Jensen
    I need to write a gui in Tkinter that can choose a csv file, read it in and generate a sequence of buttons based on the names in the first row of the csv file (later the data in the csv file should be used to run a number of simulations). So far I have managed to write a Tkinter gui that will read the csv file, but I am stomped as to how I should proceed: from Tkinter import * import tkFileDialog import csv class Application(Frame): def __init__(self, master = None): Frame.__init__(self,master) self.grid() self.createWidgets() def createWidgets(self): top = self.winfo_toplevel() self.menuBar = Menu(top) top["menu"] = self.menuBar self.subMenu = Menu(self.menuBar) self.menuBar.add_cascade(label = "File", menu = self.subMenu) self.subMenu.add_command( label = "Read Data",command = self.readCSV) def readCSV(self): self.filename = tkFileDialog.askopenfilename() f = open(self.filename,"rb") read = csv.reader(f, delimiter = ",") app = Application() app.master.title("test") app.mainloop() Any help is greatly appreciated!

  • Using the AND and NOT Operator in Python

    - by NoahClark
    Here is my custom class that I have that represents a triangle. I'm trying to write code that checks to see if self.a, self.b, and self.c are greater than 0, which would mean that I have Angle, Angle, Angle. Below you will see the code that checks for A and B, however when I use just self.a != 0 then it works fine. I believe I'm not using & correctly. Any ideas? Here is how I am calling it: print myTri.detType() class Triangle: # Angle A To Angle C Connects Side F # Angle C to Angle B Connects Side D # Angle B to Angle A Connects Side E def __init__(self, a, b, c, d, e, f): self.a = a self.b = b self.c = c self.d = d self.e = e self.f = f def detType(self): #Triangle Type AAA if self.a != 0 & self.b != 0: return self.a #If self.a > 10: #return AAA #Triangle Type AAS #elif self.a = 0: #return AAS #Triangle Type ASA #Triangle Type SAS #Triangle Type SSS #else: #return unknown

  • Python: Give a class its own `self` at instantiation time

    - by SuperDisk
    I've got a button class that you can instantiate like so: engine.createElement((0, 0), Button(code=print, args=("Stuff!",))) And when it is clicked it will print "Stuff!". However, I need the button to destroy itself whenever it is clicked. Something like this: engine.createElement((0, 0), Button(code=engine.killElement, args=(self,))) However, that would just kill the caller, because self refers to the caller at that moment. What I need to do is give the class its own 'self' in advance... I thought of just making the string 'self' refer to the self variable upon click, but what if I wanted to use the string 'self' in the arguments? What is the way to do this? Is my architecture all wrong or something? Thanks.

  • Switching to a career in Machine Learning

    - by Naive Machine Learner
    My day job is plain old software development. I am also doing my Masters in CS (part time, course based). I took a course on AI and found machine learning quite fascinating but like most courses it only offered a basic intro. I intend to learn more about Machine Learning and if possible get a job in that field. When I look at job postings in this field it is clear that a Phd in Machine learning (or prior experience in the field with considerable expertise) is required for most of them. I'm looking for advice on self learning to gain experience that'll useful in industry. At least, enough experience to get my foot in. I will do the obvious ones like reading text books, papers etc. Perhaps any open source efforts that I can participate in or something I could do on my own? Apologies if I'm being vague here but I hope there are at least a few of you who done a similar switch and can advise. Thanks !

  • First time application where to start?

    - by Nazariy
    After many years of searches and copy pasting, I'm still looking for simple solution that can transliterate text input on the fly from one key set to another. There are quite few online services that provide this feature but it still quite annoying to go online all the time. Unfortunately there is not that many applications left which are capable of doing so, and none of them supported by this day. I decided to make my own and at same time to learn something new for my self. The idea is quite simple: application should sit in system tray and wait until input language get changed, for example to Russian. If Russian language is activated, application should start to listen for user key strokes combination and replace them based on custom dictionary for example R = ?, SH = ? etc. I should be able to bind application to any installed language (Russian, Ukrainian, Bulgarian, Belarusian etc.) and customise dictionary for any of them. So my question is: Which language should I chose for this task C++, C# or might be something hardcore like Assembler, as application should work natively with Windows XP/Vista/7 or possibly Mac. (cross platform support is good but my main target is Windows) Due to nature of application behaviour how can I tell anti-virus software that it is not a "Key Logger" and basically not a virus? Where should I start and what should I be aware of? P.S. My current programming knowledge is quite basic, PHP and JavaScript with Object Oriented approach.

  • Useful certifications for a young programmer

    - by Alain
    As @Paddyslacker elegantly stated in Are certifications worth it? The main purpose of certifications is to make money for the certifying body. I am a fairly young developer, with only an undergraduate degree, and my job is (graciously) offering to sponsor some professional development of my choice (provided it can be argued that it will contribute to the quality of work I do for them). A search online offers a slew of (mostly worthless) certifications one can attain. I'm wondering if there are any that are actually recognized in the (North American) industry as an asset. My local university promoted CIPS (I.S.P., ITCP) at the time I was graduating, but for all I can tell it's just the one that happened to get its foot in the door. It's certainly money grubbing - with a $205 a year fee. So are there any such certifications that provide useful credentials? To better define 'useful' - would it benefit full time developers, or is it only something worth while to the self-employed? Would any certifications lead me to being considered for higher wages, or can that only be achieved with more experience and an higher-level degree?

  • Which algorithms/data structures should I "recognize" and know by name?

    - by Earlz
    I'd like to consider myself a fairly experienced programmer. I've been programming for over 5 years now. My weak point though is terminology. I'm self-taught, so while I know how to program, I don't know some of the more formal aspects of computer science. So, what are practical algorithms/data structures that I could recognize and know by name? Note, I'm not asking for a book recommendation about implementing algorithms. I don't care about implementing them, I just want to be able to recognize when an algorithm/data structure would be a good solution to a problem. I'm asking more for a list of algorithms/data structures that I should "recognize". For instance, I know the solution to a problem like this: You manage a set of lockers labeled 0-999. People come to you to rent the locker and then come back to return the locker key. How would you build a piece of software to manage knowing which lockers are free and which are in used? The solution, would be a queue or stack. What I'm looking for are things like "in what situation should a B-Tree be used -- What search algorithm should be used here" etc. And maybe a quick introduction of how the more complex(but commonly used) data structures/algorithms work. I tried looking at Wikipedia's list of data structures and algorithms but I think that's a bit overkill. So I'm looking more for what are the essential things I should recognize?

  • Writing Java in Java

    - by Skeith
    I have been using Java for several months at work now and am becoming mildly competent in it. The problem I think I am having is that I program C++ in Java . By that I mean I have always used C++ and am treating Java as a simple syntax change instead of appreciate if for its own language. For instance a static variable in C++ is the same as a normal variable in Java as Java is all classes so they maintain there values between function calls. Little things like this are tripping me up constantly as I am self taught. What I want is to invest the time to become a good java programmer not just a C++ programmer that can write in Java. The problem is I do not know how to do this. I have tried reading the Java doc pages but I find them very clinical and hard to understand. So what I am looking for is recommendations on how I can learn to think in Java. Books that teach Java concepts not Java syntax, online tutorials that I can work through that give it a context, established Java traditions/best practices and any other thing that you could recommend.

  • Can I eventually consider myself a professional developer if I don't have a CS degree? [on hold]

    - by heltonbiker
    Question first, context later: If I am a dedicated, self-taught programmer, always seeking top-quality books AND READING THEM, while successfully applying all that new knowledge into my current work, could I call myself (and offer my work as) a PROFESSIONAL developer? How limiting (or how common) that is nowadays? I am afraid that, no matter how hard I study and practice, it could be too difficult to compete with "actual", college graduated developers, and potential employers might have doubts investing in an "undergraduated" person. Now, context: My former profession is from healthcare sector, then I studied mechanical engineering (quit in the middle), then I studied product design (master degree), and I ended up working (very happily) at an engineering company that manufactures medical devices. For more than two years now my main activity in this company is software development. The devices contain software, and we gave up hiring software development (domain knowledge needed, too much communication cost). My current company sees a lot of value in what I do, but I cannot afford the risk of depending on this single company for the rest of my life, you get it. But a lot of job offers require some minimal formal education, usually a CS degree. Fact is that I am sure this is my target profession, I don't plan to go to another area, it is a pleasure to dive into books that normal people would consider unreadable, but I'm 36 years old and can't see going back to college as a viable alternative.

In the end my problem is adding the "tempProduct" object to the mutable array dataArray so that I can customize the table cells. Using the json framework im parsing out some json which returns an array of NSDictionary objects. Stepping through that my dictionary objects look good, I populate my custom object with properties for all my fields which goes through fine, and the values look right. However I cant add this to the array, I've tried several different implementations doesn't work. Not sure what I'm doing wrong. In some instances doing a po tempProduct prints the description and sometimes it does not. same with right clicking on the variable and choosing print description.

  • Element not found blocks execution in Selenium

    hi expert, I've written python script to scan wifi and send data to the server, I set interval value, so it keep on scanning and send the data, it read from config.txt file where i set the interval value to scan, I also add yes/no in my config file, so is 'no' it will scan only once and if 'yes' it will scan according to the interval level, my code as below import time,..... from threading import Event, Thread class RepeatTimer(Thread): def __init__(self, interval, function, iterations=0, args=[], kwargs={}): Thread.__init__(self) self.interval = interval self.function = function self.iterations = iterations self.args = args self.kwargs = kwargs self.finished = Event() def run(self): count = 0 while not self.finished.is_set() and (self.iterations <= 0 or count < self.iterations): self.finished.wait(self.interval) if not self.finished.is_set(): self.function(*self.args, **self.kwargs) count += 1 def cancel(self): self.finished.set() def scanWifi(self): #scanning process and sending data done here obj = JW() if status == "yes": t = RepeatTimer(int(intervalTime),obj.scanWifi) t.start() else: obj.scanWifi() once I package my code, its only run when I set my config file set to 'no' where it scan only once, but when I set my config file to 'yes', there is no progress at all, so I found that there is problem with my class RepeatTimer(Timer) once build, but don't know how to solve can anyone help me thanks

  • Using classes for the first time,help in debugging

    - by kaushik
    here is post my code:this is no the entire code but enough to explain my doubt.please discard any code line which u find irrelavent enter code here saving_tree={} isLeaf=False class tree: global saving_tree rootNode=None lispTree=None def __init__(self,x): file=x string=file.readlines() #print string self.lispTree=S_expression(string) self.rootNode=BinaryDecisionNode(0,'Root',self.lispTree) class BinaryDecisionNode: global saving_tree def __init__(self,ind,name,lispTree,parent=None): self.parent=parent nodes=lispTree.getNodes(ind) print nodes self.isLeaf=(nodes[0]==1) nodes=nodes[1]#Nodes are stored self.name=name self.children=[] if self.isLeaf: #Leaf Node print nodes #Set the leaf data self.attribute=nodes print "LeafNode is ",nodes else: #Set the question self.attribute=lispTree.getString(nodes[0]) self.attribute=self.attribute.split() print "Question: ",self.attribute,self.name tree={} tree={str(self.name):self.attribute} saving_tree=tree #Add the children for i in range(1,len(nodes)):#Since node 0 is a question # print "Adding child ",nodes[i]," who has ",len(nodes)-1," siblings" self.children.append(BinaryDecisionNode(nodes[i],self.name+str(i),lispTree,self)) print saving_tree i wanted to save some data in saving_tree{},which i have declared previously and want to use that saving tree in the another function outside the class.when i asked to print saving_tree it printing but,only for that instance.i want the saving_tree{} to have the data to store data of all instance and access it outside. when i asked for print saving_tree outside the class it prints empty{}.. please tell me the required modification to get my required output and use saving_tree{} outside the class..

  • Password Reset Self Service Portal

    - by Corey
    I’m looking for an affordable solution to offer a “self-service” password reset portal on the web for my active directory users. (about 150 of them) Many of them don’t use Windows workstations and therefore can’t reset there own password. I’ve been Googling, and have found so many options, that I’m not sure how to sort them all out. Has anyone had positive (or negative) experiences with any particular products?

  • Run a MySQL server in a self-contained folder

    - by codersarepeople
    I've seen many questions about how to run multiple sql servers on one server, but I would like to run mysqld as a user-level process and completely self contained in a folder (I have no permissions outside my user folder). I spent some time using the --defaults-file=my.cnf, but it still seems to conflict with the system-level mysql server that's running. Does anybody know how to do this? Thanks in advance!

  • Does Scrum turn active developers into passive developers?

    - by Saeed Neamati
    I'm a web developer working in a team of three developers and one designer. It's now about five months that we've implemented the agile scrum software development methodology. But I have a weird feeling I just wanted to share in this site. One important factor in human life is decision-making process. However, there is a big difference in decisions you make. Some decisions are just the outcome of an internal or external force, while other decisions are completely based on your free will, and some decisions are simply something in between. The more freedom you have in making decisions, the more self-driven your work would become. This seems to be a rule. Because we tend to shape our lives ourselves. There is a big difference between you deciding what to do, or being told what to do. Before scrum, I felt like having more freedom in making the decisions which were related to development, analysis, prioritizing implementation, etc. I had more feeling like I'm deciding what I'm doing. However, due to the scrum methodology, now many decisions simply come from the product owner. He prioritizes PBIs, he analyzes how the software should work, even sometimes how the UI and functionality should be implemented. I know that this is part of the scrum methodology, and I also know that this may result in better sales of product in future. However, I now feel like I'm always getting told to do something, instead of deciding to do something. This syndrome now has made me more passive towards the work. I tend to search less to find a better solution, approach, or technique I don't wake up in the morning expecting to get to an enjoyable work. Rather, I feel like being forced to work in order to live I have more hunger to work on my own hobby projects after work I won't push the team anymore to get to the higher technological levels I spend more time now on dinner, or tea-times and have less enthusiasm to get back to work I'm now willing more for the work to finish sooner, so that I can get home The big problem is, I see and diagnose this behavior in my colleagues too. Is it the outcome of scrum? Does scrum really makes the development team feel like they have no part in forming the overall software, thus making the passive to the project? How can I overcome this feeling?

  • Career Change Need Advice: Professional Web Developer

    - by bikedorkseattle
    I'm hoping to get some advice here on the steps I should take to make a career change into professional web development. I've been working in cancer research the last 14 years and I need a change. The job market is terrible, the pay is worse, and despite what one would think the atmosphere is generally un-collegial, even in your own group. Venture funding never returned after the dot com burst and with 3 to 5 wars our country is now in, NIH funding is only going to get worse. I know things are not going to get better for my field, sadly, and I know I need to move on. For probably just as long I have fiddled around with web development, I even run a fairly popular site with close to 1 million/month pageviews that pulls a decent income, but not stable enough to live off of right now. My skills are ok for being self taught. I enjoy the fast paced nature of the web and the tools the community creates and how eager people are to help and share knowledge; it's what science should be. I have been trying to find an entry level developer job doing standard HTML/CSS/PHP/MySQL/JS/jQuery type work. A good 50%+ of the jobs want someone with a CS degree, and most want 5 years experience. Having no professional experience and no formal education, I know I'm at a huge disadvantage. I am now considering my options on how to move forward professionally. The way I see it I have basically 3 options. Build up my portfolio of work as much as I can and continue to learn as much as I can on my own. Try to contribute on some open source project when time allows. Network like crazy and go to meetups. Be confident and pray a lot in private. OR While doing above, do some certification programs in PHP and Java, possibly others. Get a Zend Certification. OR Spend a few years getting a CS degree while doing 1. I've already done the work fulltime go to school thing and it doesn't excite me one bit. I didn't have the greatest college experience and am not too eager to return, but I have a family to feed. Is the degree really necessary or is it more of a right of passage type thing in most instances? I appreciate everyones input. Thanks for taking the time to respond.
