• First programming language: PHP, Ruby, Python?

  - by Victor

  I've been a Web developer for over 5 years and am looking to start building more complex Web apps. Currently, I know HTML/CSS/Javascript but I feel it's time to start learning something else. I work with a lot of applications based on PHP. I created a vBulletin forum on my own time and I would definitely want to build off of that since it has gained a bit of popularity. I also work with Wordpress quite often. All of the software I work with tends to be based on PHP but I hear a lot of people say Ruby or Python is better. Since I'm starting out, I really don't care which one I learn but I want to start right. Any recommendations for someone with HTML/CSS/Javascript knowledge but wants to branch out?

• Python: Elegant way to check if at least one regex in list matches a string

  - by houbysoft

  Hi. I have a list of regexes in python, and a string. Is there an elegant way to check if the at least one regex in the list matches the string? By elegant, I mean something better than simply looping through all of the regexes and checking them against the string and stopping if a match is found. Basically, I had this code: list = ['something','another','thing','hello'] string = 'hi' if string in list: pass # do something else: pass # do something else Now I would like to have some regular expressions in the list, rather than just strings, and I am wondering if there is an elegant solution to check for a match to replace if string in list:. Thanks in advance.

• Parsing dbpedia JSON in Python

  - by givp

  Hello, I'm trying to get my head around the dbpedia JSON schema and can't figure out an efficient way of extracting a specific node: This is what dbpedia gives me: http://dbpedia.org/data/Ceramic_art.json I've got the whole thing as a JSON object in Python but don't really understand how to get the english abstract from this data. I've gotten this far: u = "http://dbpedia.org/data/Ceramic_art.json" data = urlfetch.fetch(url=u) json_data = json.loads(data.content) for j in json_data["http://dbpedia.org/resource/Ceramic_art"]: if(j == "http://dbpedia.org/ontology/abstract"): print "it's here" Not sure how to proceed from here. As you can see there are multiple languages. I need to get the english abstract. Thanks for your help, g

• Manipulating binary data in Python

  - by Dominic Bou-Samra

  I am opening up a binary file like so: file = open("test/test.x", 'rb') and reading in lines to a list. Each line looks a little like: '\xbe\x00\xc8d\xf8d\x08\xe4.\x07~\x03\x9e\x07\xbe\x03\xde\x07\xfe\n' I am having a hard time manipulating this data. If I try and print each line, python freezes, and emits beeping noises (I think there's a binary beep code in there somewhere). How do I go about using this data safely? How can I convert each hex number to decimal?

• taking intersection of N-many lists in python

  - by user248237

  what's the easiest way to take the intersection of N-many lists in python? if I have two lists a and b, I know I can do: a = set(a) b = set(b) intersect = a.intersection(b) but I want to do something like a & b & c & d & ... for an arbitrary set of lists (ideally without converting to a set first, but if that's the easiest / most efficient way, I can deal with that.) I.e. I want to write a function intersect(*args) that will do it for arbitrarily many sets efficiently. What's the easiest way to do that? EDIT: My own solution is reduce(set.intersection, [a,b,c]) -- is that good? thanks.

• Unable to access LinkedIn conections using python rauth library

  - by srinath sastry

  I was trying out this example at https://github.com/litl/rauth/blob/master/examples/linkedin-web.py I get a 403, Access to connections denied error and it returns KeyError: '_total'. r_network option is present. Has anyone faced this issue? Also if you look at http://docs.python-requests.org/en/latest/user/quickstart/#oauth-authentication, the 'requests' library is initializing resource_owner_key, resource_owner_secret apart from the application keys. Not sure how these are getting passed from the 'rauth' library, Was wondering if that was causing this 403 error.

• Python Scraper for Javascript?

  - by Diego

  Hey all, Can anyone direct me to a good Python screen scraping library for javascript code (hopefully one with good documentation/tutorials)? I'd like to see what options are out there, but most of all the easiest to learn with fastest results... wondering if anyone had experience. I've heard some stuff about spidermonkey, but maybe there are better ones out there? Specifically, I use BeautifulSoup and Mechanize to get to here, but need a way to open the javascript popup, submit data, and download/parse the results in the javascript popup. <a href="javascript:openFindItem(12510109)" onclick="s_objectID=&quot;javascript:openFindItem(12510109)_1&quot;;return this.s_oc?this.s_oc(e):true">Find Item</a> I'd like to implement this with Google App engine and Django. Thanks!

• python - checking if a user has admin privileges

  - by Matt

  Hi, I'm writing a little program as a self-learning project in Python 3.x. my idea is for the program to allow two fields of text entry to the user, and then plug the user's input into the value of two specific registry keys. What I was wondering, and something my books don't seem to cover, is if there is a simple way to make it check if the current user can access the registry. I'd rather it cleanly tell the user that he needs admin privileges than for the program to go nuts and crash because it's trying to access a restricted area. I'd like it to make this check as soon as the program launches, before the user is given any input options. What code is needed for this? thanks for the help

• Building a minimal plugin architecture in Python.

  - by dF

  I have an application, written in Python, which is used by a fairly technical audience (scientists). I'm looking for a good way to make the application extensible by the users, i.e. a scripting/plugin architecture. I am looking for something extremely lightweight. Most scripts, or plugins, are not going to be developed and distributed by a third-party and installed, but are going to be something whipped up by a user in a few minutes to automate a repeating task, add support for a file format, etc. So plugins should have the absolute minimum boilerplate code, and require no 'installation' other than copying to a folder (so something like setuptools entry points, or the Zope plugin architecture seems like too much.) Are there any systems like this already out there, or any projects that implement a similar scheme that I should look at for ideas / inspiration?

• Google Application Engine slow in case of Python...

  - by Aftershock

  hi, I am reading a "table" in Python in GAE that has 1000 rows and the program stops because the time limit is reached. (So it takes at least 20 seconds.)( Is that possible that GAE is that slow? Is there a way to fix that? Is this because I use free service and I do not pay for it? Thank you. The code itself is this: for u in userall: # userall has 1000 users for stockname in stocknamesall: # 4 stocks astock= stocksowned() astock.quantity = random.randint(1,100) astock.nameid = u.key() astock.stockid = stockname.key() liststocks.append(astock);

  I have a request that maps to this class ChatMsg It takes in 3 get variables, username, roomname, and msg. But it fails on this last line here. class ChatMsg(webapp.RequestHandler): # this is line 239 def get(self): username = urllib.unquote(self.request.get('username')) roomname = urllib.unquote(self.request.get('roomname')) # this is line 242 When it tries to assign roomname, it tells me: <type 'exceptions.NameError'>: name 'self' is not defined Traceback (most recent call last): File "/base/data/home/apps/chatboxes/1.341998073649951735/chatroom.py", line 239, in <module> class ChatMsg(webapp.RequestHandler): File "/base/data/home/apps/chatboxes/1.341998073649951735/chatroom.py", line 242, in ChatMsg roomname = urllib.unquote(self.request.get('roomname')) what the hell is going on to make self not defined

• Python proper use of __str__ and __repr__

  - by Peter

  Hey, My current project requires extensive use of bit fields. I found a simple, functional recipe for bit a field class but it was lacking a few features I needed, so I decided to extend it. I've just got to implementing __str__ and __repr__ and I want to make sure I'm following convention. __str__ is supposed to be informal and concice, so I've made it return the bit field's decimal value (i.e. str(bit field 11) would be "3". __repr__ is supposed to be a official representation of the object, so I've made it return the actual bit string (i.e. repr(bit field 11) would be "11"). In your opinion would this implementation meet the conventions for str and repr? Additionally, I have used the bin() function to get the bit string of the value stored in the class. This isn't compatible with Python < 2.6, is there an alternative method? Cheers, Pete

• Why is this logical expression in python False?

  - by W3ctor

  My question is, why are these expressions False? Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) [GCC 4.4.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> num = raw_input("Choose a number: ") Choose a number: 5 >>> print num 5 >>> print ( num < 18 ) False >>> print ( num == 5 ) False Because if i try this: >>> print ( num > 0 ) True The expression works fine. Thank you for the help!

• Python's urllib2 don't work on some sites

  - by Binny V A

  I found that you can't read from some sites using Python's urllib2(or urllib). An example... urllib2.urlopen("http://www.dafont.com/").read() # Returns '' These sites works when you visit the site. I can even scrap them using PHP(didn't try other languages). I have seen other sites with the same issue - but can't remember the URL at the moment. My questions are... What is the cause of this issue? Any workaround for this issue?

• Python faster way to read fixed length fields form a file into dictionary

  - by Martlark

  I have a file of names and addresses as follows (example line) OSCAR ,CANNONS ,8 ,STIEGLITZ CIRCUIT And I want to read it into a dictionary of name and value. Here self.field_list is a list of the name, length and start point of the fixed fields in the file. What ways are there to speed up this method? (python 2.6) def line_to_dictionary(self, file_line,rec_num): file_line = file_line.lower() # Make it all lowercase return_rec = {} # Return record as a dictionary for (field_start, field_length, field_name) in self.field_list: field_data = file_line[field_start:field_start+field_length] if (self.strip_fields == True): # Strip off white spaces first field_data = field_data.strip() if (field_data != ''): # Only add non-empty fields to dictionary return_rec[field_name] = field_data # Set hidden fields # return_rec['_rec_num_'] = rec_num return_rec['_dataset_name_'] = self.name return return_rec

• Python 2.6, 3 abstract base class misunderstanding

  - by Aaron

  I'm not seeing what I expect when I use ABCMeta and abstractmethod. This works fine in python3: from abc import ABCMeta, abstractmethod class Super(metaclass=ABCMeta): @abstractmethod def method(self): pass a = Super() TypeError: Can't instantiate abstract class Super ... And in 2.6: class Super(): __metaclass__ = ABCMeta @abstractmethod def method(self): pass a = Super() TypeError: Can't instantiate abstract class Super ... They both also work fine (I get the expected exception) if I derive Super from object, in addition to ABCMeta. They both "fail" (no exception raised) if I derive Super from list. I want an abstract base class to be a list but abstract, and concrete in sub classes. Am I doing it wrong, or should I not want this in python?

• How to override built-in getattr in Python?

  - by Stephen Gross

  I know how to override an object's getattr() to handle calls to undefined object functions. However, I would like to achieve the same behavior for the builtin getattr() function. For instance, consider code like this: call_some_undefined_function() Normally, that simply produces an error: Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'call_some_undefined_function' is not defined I want to override getattr() so that I can intercept the call to "call_some_undefined_function()" and figure out what to do. Is this possible? Thanks, --Steve

• Comment out a python code block

  - by gbarry

  Is there any mechanism to comment out large blocks of Python code? Right now the only ways I can see of commenting out code are to either start every line with a #, or to enclose the code in """ (triple quotes), except that actually makes it show up in various doc tools. Edit--After reading the answers (and referring to the "duplicate"), I have concluded the correct answer is "No". One person said so, and the rest lectured us about editors. Not a bad thing, but I feel it's important to put the answer at the top.

• python class attribute

  - by chnet

  Hi, i have a question about class attribute in python. class base : def __init__ (self): pass derived_val = 1 t1 = base() t2 = base () t2.derived_val +=1 t2.__class__.derived_val +=2 print t2.derived_val # its value is 2 print t2.__class__.derived_val # its value is 3 The results are different. I also use id() function to find t2.derived_val and t2.class.derived_val have different memory address. My problem is derived_val is class attribute. Why it is different in above example? Is it because the instance of class copy its own derived_val beside the class attribute?

• "Streaming" MJPG using python.

  - by tyler

  I have a webcam that I want to do some image processing on using Python. It's coming through as a Motion-JPEG. I want to try to process the stuff "live," but really what I want to do is this: Open the URL, start data streaming to some buffer... Read x bytes (where x is image size) to an image Process that image Display in result panel Return to number 2 The problem is that, while I do have the resolution, I have no idea how many bytes to read. I've tried googling the M-JPEG specification but can't find anything on if the images are separated by some header or what. Anybody have any ideas?

• Sqlite and Python -- return a dictionary using fetchone()?

  - by AndrewO

  I'm using sqlite3 in python 2.5. I've created a table that looks like this: create table votes ( bill text, senator_id text, vote text) I'm accessing it with something like this: v_cur.execute("select * from votes") row = v_cur.fetchone() bill = row[0] senator_id = row[1] vote = row[2] What I'd like to be able to do is have fetchone (or some other method) return a dictionary, rather than a list, so that I can refer to the field by name rather than position. For example: bill = row['bill'] senator_id = row['senator_id'] vote = row['vote'] I know you can do this with MySQL, but does anyone know how to do it with SQLite? Thanks!!!

• Calling a method with getattr in Python

  - by brain_damage

  How to call a method using getattr? I want to create a metaclass, which can call non-existing methods of some other class that start with the word 'oposite_'. The method should have the same number of arguments, but to return the opposite result. def oposite(func): return lambda s, *args, **kw: not oposite(s, *args, **kw) class Negate(type): def __getattr__(self, name): if name.startswith('oposite_'): return oposite(self.__getattr__(name[8:])) def __init__(self,*args,**kwargs): self.__getattr__ = Negate.__getattr__ class P(metaclass=Negate): def yep(self): return True But the problem is that self.__getattr__(sth) returns a NoneType object. >>> p = P() >>> p.oposite_yep() Traceback (most recent call last): File "<pyshell#115>", line 1, in <module> p.oposite_yep() TypeError: <lambda>() takes at least 1 positional argument (0 given) How to deal with this?
