• Find unused import statements in Java source

  - by curiousmind

  Does anyone know of a tool (besides Eclipse or any other IDE) that I can use to find unused imports in a Java source file? I am looking for a command-line type of tool (to integrate in a larger script). Thank you.

• How to convert JavaScript dictionary into Python syntax

  - by Sputnix

  Writing out javascript dictionary from inside of JavaScript- enabled application (such as Adobe) into external .jsx file (or any other .txt file) the context of resulted file dictionary looks like: ({one:"1", two:"2"}) (Please note that each dictionary keys are written as they are the variables name (which is not true). A next step is to read this .jsx file with Python. I need to find a way to convert ({one:"1", two:"2"}) into Python dictionary syntax such as: {'one':"1", 'two':"2"} It has been already suggested that instead of using JavaScript's built-in dict.toSource() it would make more sense to use JSON which would write a dictionary content in similar to Python syntax. But unfortunately using JSON is not an option for me. I need to find a way to convert ({one:"1", two:"2"}) into {'one':"1", 'two':"2"} using Python alone. Any suggestions on how to achieve it? Once again, the problem mostly in dictionary keys syntax which inside of Python look like variable names instead of strings-like dictionary keys names: one vs "one"

• Import Error when use templatetags in Django

  - by zmfantasy

  Well, when I'm trying to use 'inclusion' in Django, I met some confused problems that I can't solve it by myself. There is the structures for my project. MyProject--- App1--- __init__.py models.py test.py urls.py views.py App2--- ... template--- App1--- some htmls App2--- ... templatetags--- __init__.py inclusion_test.py manage.py urls.py __init__.py settings.py I have registered templatetags folder in the settings.py (Both in Installed APPS & TEMPLATE_DIRS). But when I want to use {% load inclusion_test %} in my html, it raise an exception like this: 'inclusion_cld_tags' is not a valid tag library: Could not load template library from django.templatetags.inclusion_cld_tags, No module named inclusion_cld_tags I think there is nothing wrong with my import work, how can I do with that? Thanks for help! My django version: 1.0+ My Python version: 2.6.4

• Calculating the pixel size of a string with Python

  - by Aristide

  I have a Python script which needs to calculate the exact size of arbitrary strings displayed in arbitrary fonts in order to generate simple diagrams. I can easily do it with Tkinter. The problem is the results seem to depend on the version of Python and/or the system. import Tkinter as tk import tkFont root = tk.Tk() times12 = tkFont.Font(family="times",size=12) print times12.metrics("linespace"), print times12.measure("Hello world") times24 = tkFont.Font(family="times",size=24) print times24.metrics("linespace"), print times24.measure("Hello world") Python 2.5 on Mac OS X gives the actual pixel measurements: 12 57 24 116 Python 2.6.1 on Mac OS X gives: 14 58 27 115 Python 2.6.3 on Windows XP gives: 19 71 36 154 Such a need being quite common, I suspect I did something wrong. Any idea?

• Exposing classes inside modules within a Python package directly in the package's namespace

  - by Richard Waite

  I have a wxPython application with the various GUI classes in their own modules in a package called gui. With this setup, importing the main window would be done as follows: from gui.mainwindow import MainWindow This looked messy to me so I changed the __init__.py file for the gui package to import the class directly into the package namespace: from mainwindow import MainWindow This allows me to import the main window like this: from gui import MainWindow This looks better to me aesthetically and I think it also more closely represents what I'm doing (importing the MainWindow class from the gui "namespace"). The reason I made the gui package was to keep all the GUI stuff together. I could have just as easily made a single gui module and stuffed all the GUI classes in it, but I think that would have been unmanageable. The package now appears to work like a module, but allows me to separate the classes into their own modules (along with helper functions, etc.). This whole thing strikes me as somewhat petty, I just thought I'd throw it out there to see what others think about the idea.

• Import XCode project inside another XCode project

  - by bruno

  I imported an XCode project inside another XCode project. I dragged and dropped project B inside project A like in How to Call Xcode Project In Another Xcode Project.......? Next, i imported a class from project B in project A, so i could use a method but i gave me an error "ClassTemp.h' file not found". From what i´ve read this should have worked. Do i have to do some kind of configuration for it to work?

• Why is Decimal('0') > 9999.0 True in Python?

  - by parxier

  This is somehow related to my question Why is ''0 True in Python? In Python 2.6.4: >> Decimal('0') > 9999.0 True From the answer to my original question I understand that when comparing objects of different types in Python 2.x the types are ordered by their name. But in this case: >> type(Decimal('0')).__name__ > type(9999.0).__name__ False Why is Decimal('0') > 9999.0 == True then? UPDATE: I usually work on Ubuntu (Linux 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:05:19 UTC 2010 i686 GNU/Linux, Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) [GCC 4.4.1] on linux2).

• How to import and export only data of whole database in access 2007

  - by DiegoMaK

  Hi, I have two identical databases with same structure, database a in computer a and database b in computer b. The data of database a*(a.accdb)* and database b*(b.accdb)* are different. then in database a i have for example ID:1, 2, 3 and in database B i Have ID:4,5,6 Then i need merge these databases data in only one database(a or b, doesn't matter) so the final database looks like. ID:1,2,3,4,5,6 I search an easy way to do this. because i have many tables. and do this by union query is so tedious. I search for example for a backup option for only data without scheme as in postgreSQl or many others RDBMS, but i don't see this options in access 2007. pd:only just table could be duplicate values(i guess that pk doesn't allow copy a duplicate value and all others values will be copied well). if i wrong please correct me. thanks for your help.

  I have method that returns module path of given class name def findModulePath(path, className): attributes = [] for root, dirs, files in os.walk(path): for source in (s for s in files if s.endswith(".py")): name = os.path.splitext(os.path.basename(source))[0] full_name = os.path.splitext(source)[0].replace(os.path.sep, '.') m = imp.load_module(full_name, *imp.find_module(name, [root])) try: attr = getattr(m, className) attributes.append(attr) except: pass if len(attributes) <= 0: raise Exception, "Class %s not found" % className for element in attributes: print "%s.%s" % (element.__module__, className) but it does not return the full path of the module, For example I have a python file named "objectmodel" in objects package,and it contains a Model class, So I call findModulePath(MyProjectPath,"Model"). it prints objectmodel.Model but I need objects.objectmodel.Model

• Python implementation of avro slow?

  - by lazy1

  I'm reading some data from avro file using the avro library. It takes about a minute to load 33K objects from the file. This seem very slow to me, specially with the Java version reading the same file in about 1sec. Here is the code, am I doing something wrong? import avro.datafile import avro.io from time import time def load(filename): fo = open(filename, "rb") reader = avro.datafile.DataFileReader(fo, avro.io.DatumReader()) for i, record in enumerate(reader): pass return i + 1 def main(argv=None): import sys from argparse import ArgumentParser argv = argv or sys.argv parser = ArgumentParser(description="Read avro file") start = time() num_records = load("events.avro") end = time() print("{0} records in {1} seconds".format(num_records, end - start)) if __name__ == "__main__": main()

• Python, Raspberry, and Arduino Communication

  - by user2924156

  I have been working with my Raspberry, Arduino and applying some Python to make them communicate. I also installed pyserial. If I use IDLE and try the following I get my expected results. >>> import serial >>> ser = serial.Serial('/dev/ttyUSB0',115200) >>> ser.write('x:1\n') 8 >>> ser.readline() 'X:1\r\n' If I write a python scrip and run it I don't get anything back. Here is my python script. import serial ser = serial.Serial('/dev/ttyUSB0', 115200) ser.write('!x:1\n') ser.readline() I am new to Python so looking for some help to understand they this works in IDLE but not as a python script run from terminal. Thanks.

• Update Params in Python During Infinite Loop

  - by python Dude

  Hello, I was hoping to get some help on a question. I have an infinite loop that I need run and I need to update a set of variables (x in this case) at random times from the command-line. Is there any way to do this? For example: x = 0 while True: x = x + 1 if x < 30: do something and I need to update x's value from the command-line periodically

• Realtime processing and callbacks with Python and C++

  - by Doughy

  I need to write code to do some realtime processing that is fairly computationally complex. I would like to create some Python classes to manage all my scripting, and leave the intensive parts of the algorithm coded in C++ so that they can run as fast as possible. I would like to instantiate the objects in Python, and have the C++ algorithms chime back into the script with callbacks in python. Something like: myObject = MyObject() myObject.setCallback(myCallback) myObject.run() def myCallback(val): """Do something with the value passed back to the python script.""" pass Will this be possible? How can I run a callback in python from a loop that is running in a C++ module? Anyone have a link or a tutorial to help me do this correctly?

• Projects to learn Python

  - by Andrew

  I know this isn't a question about a specific snippet of code or anything, but here goes - I've been messing around with the idea of learning Python since I'm pretty bored with PHP (and web development in general), but I can't think of any projects to help me learn. I've already worked through some of Project Euler with Python, but it's getting old. I know the basics, and I want to write something more fun that will introduce me to new things in Python. Is there a cliche beginner project for Python? (for example, PHP's would be a blog or something similiar) Are there any common Python projects for newcomers, or any uncommon ones that you'd suggest? Any ideas would help.

• SWIG: Throwing exceptions from Python to C++

  - by wheaties

  We've got an interface we've defined in C++ (abstract class, all functions pure virtual) which will be extended in Python. To overcome the cross-language polymorphism issues we're planning on using SWIG directors. I've read how to catch exceptions thrown from C++ code in our Python code here, here, here, and even on SO. It's fairly straight forward and I'm not expecting issues with handling our library's own exceptions. What I'd like to know and can't seem to find in the documentation is how to have our Python implementation of the extended C++ interface throw those C++ exceptions in a way that makes them visible to the C++ code. We could make small functions within the *.i files such that each function throws our exceptions: void throw_myException(){ throw MyException; } but I'm wondering how it will interact with the Python code. Anyone have any experience with throwing C++ exceptions from Python code?

• python how to put data on y-axis when plotting histogram

  - by user3041107

  I don't quite understand how to control y - axis when using plt.hist plot in python. I read my .txt data file - it contains 10 columns with various data. If I want to plot distribution of strain on x axis I take column n.5. But what kind of value appears on y axis ??? Don't understand that. here is the code: import numpy import matplotlib.pyplot as plt from pylab import * from scipy.stats import norm import sys strain = [] infile = sys.argv[1] for line in infile: ret = numpy.loadtxt(infile) strain += list(ret[:,5]) fig = plt.figure() plt.hist(strain, bins = 20) plt.show() Thanks for help!

• How do I stop Python install on Mac OS X from putting things in my home directory?

  - by Rob

  Hi, I'm trying to install Python from source on my Mac. (OS X 10.6.2, Python-2.6.5.tar.bz2) I've done this before and it was easy, but for some reason, this time after ./configure, and make, the sudo make install puts things some things in my home directory instead of in /usr/local/... where I expect. The .py files are okay, but not the .so files... RobsMac Python-2.6.5 $ sudo make install [...] /usr/bin/install -c -m 644 ./Lib/anydbm.py /usr/local/lib/python2.6 /usr/bin/install -c -m 644 ./Lib/ast.py /usr/local/lib/python2.6 /usr/bin/install -c -m 644 ./Lib/asynchat.py /usr/local/lib/python2.6 [...] running build_scripts running install_lib creating /Users/rob/Library/Python creating /Users/rob/Library/Python/2.6 creating /Users/rob/Library/Python/2.6/site-packages copying build/lib.macosx-10.4-x86_64-2.6/_AE.so - /Users/rob/Library/ Python/2.6/site-packages copying build/lib.macosx-10.4-x86_64-2.6/_AH.so - /Users/rob/Library/ Python/2.6/site-packages copying build/lib.macosx-10.4-x86_64-2.6/_App.so - /Users/rob/Library/ Python/2.6/site-packages [...] Later, this causes imports that require those .so files to fail. For example...

• Python for a hobbyist programmer ( a few questions)

  - by Matt

  I'm a hobbyist programmer (only in TI-Basic before now), and after much, much, much debating with myself, I've decided to learn Python. I don't have a ton of free time to teach myself a hundred languages and all programming I do will be for personal use or for distributing to people who need them, so I decided that I needed one good, strong language to be good at. My questions: Is python powerful enough to handle most things that a typical programmer might do in his off-time? I have in mind things like complex stat generators based on user input for tabletop games, making small games, automate install processes, and build interactive websites, but probably a hundred things along those lines Does python handle networking tasks fairly well? Can python source be obscufated (mispelled I think), or is it going to be open-source by nature? The reason I ask this is because if I make something cool and distribute it, I don't want some idiot script kiddie to edit his own name in and say he wrote it And how popular is python, compared to other languages. Ideally, my language would be good and useful with help found online without extreme difficulty, but not so common that every idiot with computer knows python. I like the idea of knowing a slightly obscure language. Thanks a ton for any help you can provide.

• Sentiment analysis for twitter in python

  - by Ran

  I'm looking for an open source implementation, preferably in python, of Textual Sentiment Analysis (http://en.wikipedia.org/wiki/Sentiment_analysis). Is anyone familiar with such open source implementation I can use? I'm writing an application that searches twitter for some search term, say "youtube", and counts "happy" tweets vs. "sad" tweets. I'm using Google's appengine, so it's in python. I'd like to be able to classify the returned search results from twitter and I'd like to do that in python. I haven't been able to find such sentiment analyzer so far, specifically not in python. Are you familiar with such open source implementation I can use? Preferably this is already in python, but if not, hopefully I can translate it to python. Note, the texts I'm analyzing are VERY short, they are tweets. So ideally, this classifier is optimized for such short texts. BTW, twitter does support the ":)" and ":(" operators in search, which aim to do just this, but unfortunately, the classification provided by them isn't that great, so I figured I might give this a try myself. Thanks! BTW, an early demo is here and the code I have so far is here and I'd love to opensource it with any interested developer.

• What is the most platform- and Python-version-independent way to make a fast loop for use in Python?

  - by Statto

  I'm writing a scientific application in Python with a very processor-intensive loop at its core. I would like to optimise this as far as possible, at minimum inconvenience to end users, who will probably use it as an uncompiled collection of Python scripts, and will be using Windows, Mac, and (mainly Ubuntu) Linux. It is currently written in Python with a dash of NumPy, and I've included the code below. Is there a solution which would be reasonably fast which would not require compilation? This would seem to be the easiest way to maintain platform-independence. If using something like Pyrex, which does require compilation, is there an easy way to bundle many modules and have Python choose between them depending on detected OS and Python version? Is there an easy way to build the collection of modules without needing access to every system with every version of Python? Does one method lend itself particularly to multi-processor optimisation? (If you're interested, the loop is to calculate the magnetic field at a given point inside a crystal by adding together the contributions of a large number of nearby magnetic ions, treated as tiny bar magnets. Basically, a massive sum of these.) # calculate_dipole # ------------------------- # calculate_dipole works out the dipole field at a given point within the crystal unit cell # --- # INPUT # mu = position at which to calculate the dipole field # r_i = array of atomic positions # mom_i = corresponding array of magnetic moments # --- # OUTPUT # B = the B-field at this point def calculate_dipole(mu, r_i, mom_i): relative = mu - r_i r_unit = unit_vectors(relative) #4pi / mu0 (at the front of the dipole eqn) A = 1e-7 #initalise dipole field B = zeros(3,float) for i in range(len(relative)): #work out the dipole field and add it to the estimate so far B += A*(3*dot(mom_i[i],r_unit[i])*r_unit[i] - mom_i[i]) / sqrt(dot(relative[i],relative[i]))**3 return B
