  • Are any of these quad-tree libraries any good?

    - by Noctis Skytower
    It appears that a certain project of mine will require the use of quad-trees, something that I have never worked with before. From what I have read they should allow substantial performance enhancements than a brute-force attempt at the problem would yield. Are any of these python modules any good? Quadtree 0.1.2 <= No: unable to execute in Python 3.1 QuadTree <= Yes: simple while working with rectangles quadtree.py <= No: no support for needed operations EDIT: Does anyone know of a better implementation that the one presented on the pygame wiki article?

  • Changes to the User Permissions Not saving

    - by anru
    I am use drupal 6. it seems like permission page can not save too many settings. I have try to save permission setting, but it is just not saved into DB. I have found out this is due to "too many fields". (use content permission module). if i uncheck some fields, and then checking lesser fields, permission will be saved. for example, if I am unchecking 2 check boxes, then checking one check box, permission will be saved. does any one know which function the permission page used to insert result into db? my php memory limit is 256M.

  • Measuring CPU time per-thread on Windows

    - by Eli Courtwright
    I'm developing a long-running multi-threaded Python application for Windows, and I want the process to know the CPU time that each of its threads has taken. I can get the overall times for the entire process with os.times() but I need to know the per-thread times. I know that there are external tools such as the Sysinternals Process Explorer, but my program itself needs to have this information. If I were on Linux, I look in the /proc filesystem, as described here. If I were writing C code, I'd use the GetThreadTimes call, as described here. So how can I accomplish this on Windows using Python?

  • IO completion port key confusion

    - by Richard Tew
    I'm writing an IO completion port based server (source code here) using the Windows DLL API in Python using the ctypes module. But this is a pretty direct usage of the API and this question is directed at those who have a knowledge of IOCP, not Python. As I understand the documentation for CreateIoCompletionPort, you specify your "user defined" completion key when you call this function with a file handle (in my case a socket) you are associating with the created IOCP. When you get around to calling GetQueuedCompletionStatus, you get a completion key value along with a pointer to an overlapped object. The completion key should identify what overlapped object and request has completed. However, let's say I pass in 100 as the completion key in my CreateIoCompletionPort call with an overlapped object. When the same overlapped object has its IO completed and it arrives back through GetQueuedCompletionStatus, the completion key that accompanies it is much larger and bares no resemblance to the original value of 100. Am I misunderstanding how the completion key works, or must I be doing it wrong in the source code I linked above?

  • How can i set isdigit() command as a variable?

    - by Nick
    I'm new to python but I caught on to the basics pretty quick and decided to start trying to make a program while I'm still learning, since I learn best by actually doing things. So I'm making a program in python that will add polynomials and I need to see if a character from the parser is numeric im using the isdigit() command. Instead of having to type isdigit() all the time in my code such as n.isdigit(), I want to assign it to a variable t = 'isdigit()' and then type n.t. This doesn't work, so is there an alternative to not typing the whole command?

  • Application with both console and gui mode

    - by mridang
    Hi, I have a python console app. Like most python console apps it uses the OptionParser module to take arguments. I've now developed a GUI for my app using wxPython and i'd like to integrate the two. I'd like my app to be run both from the console and from the OS's UI. When it is invoked from the console it runs as a console app and when it is double clicked in the OS's UI, it runs as a GUI app. How could I do something like this? Could someone show me a a snippet of what the __main__ block should be like? Thanks a ton.

  • Is there a recommended command for "hg bisect --command"?

    - by blokeley
    I have an emergent bug that I've got to track down tomorrow. I know a previous hg revision which was good so I'm thinking about using hg bisect. However, I'm on Windows and don't want to get into DOS scripting. Ideally, I'd be able to write a Python unit test and have hg bisect use that. This is my first attempt. bisector.py #!/usr/bin/env python import sys import unittest class TestCase(unittest.TestCase): def test(self): #raise Exception('Exception for testing.') #self.fail("Failure for testing.") pass def main(): suite = unittest.defaultTestLoader.loadTestsFromTestCase(TestCase) result = unittest.TestResult() suite.run(result) if result.errors: # Skip the revision return 125 if result.wasSuccessful(): return 0 else: return 1 if '__main__' == __name__: sys.exit(main()) Perhaps I could then run: hg bisect --reset hg bisect --bad hg bisect --good -r 1 hg bisect --command=bisector.py Is there a better way of doing it? Thanks for any advice.

  • How do I get PyLint to find namespace packages?

    - by tjd.rodgers
    I have a virtualenv where I've installed two packages, both using the company.project_name namespace. So the first package is importable from company.project_name.one and the second from company.project_name.two. The challenge is that I can't seem to be able to run PyLint on either one of them. If I issue: $ pylint company.project_name.one I get: ************* Module company.project_name.one F: 1, 0: No module named project_name.one(fatal) I suspect that I'm probably doing something wrong. Is there a proper way to do this? Edit: I should have made it clear that company.project_name and company are namespace packages and not regular packages.

  • I have a generic implementation of PHP mcrypt module and its not decrypting

  • Using jep.invoke() method

    - by hofsoc
    Hi, I need to call a function from a python script and pass in parameters into it. I have a test python script which I can call and run from java using Jepp - this then adds the person. Eg Test.py import Finding from Finding import * f = Finding() f.addFinding("John", "Doe", 27) Within my Finding class I have addFinding(firstname, lastName, age) However, I wish to be able to do this from within java. Should I be using the jep.invoke() method. Does anyone have a hello world example of such a thing being done or forward me to some good examples? Does anyone have any suggestions please? Thanks in advance

  • Sphinx autodoc is not automatic enough

    - by Cory Walker
    I'm trying to use Sphinx to document a 5,000+ line project in Python. It has about 7 base modules. As far as I know, In order to use autodoc I need to write code like this for each file in my project: .. automodule:: mods.set.tests :members: :show-inheritance: This is way too tedious because I have many files. It would be much easier if I could just specify that I wanted the 'mods' module to be documented. Sphinx could then recursively go through the module and make a page for each submodule. Is there A feature like this? If not I could write a script to make all the .rst files, but that would take up a lot of time.

  • How can I get my setup.py to use a relative path to my files?

    - by Chris B.
    I'm trying to build a Python distribution with distutils. Unfortunately, my directory structure looks like this: /code /mypackage __init__.py file1.py file2.py /subpackage __init__.py /build setup.py Here's my setup.py file: from distutils.core import setup setup( name = 'MyPackage', description = 'This is my package', packages = ['mypackage', 'mypackage.subpackage'], package_dir = { 'mypackage' : '../mypackage' }, version = '1', url = 'http://www.mypackage.org/', author = 'Me', author_email = '[email protected]', ) When I run python setup.py sdist it correctly generates the manifest file, but doesn't include my source files in the distribution. Apparently, it creates a directory to contain the source files (i.e. mypackage1) then copies each of the source files to mypackage1/../mypackage which puts them outside of the distribution. How can I correct this, without forcing my directory structure to conform to what distutils expects?

  • numpy array C api

    - by wiso
    I have a C++ function returning a std::vector and I want to use it in python, so I'm using the C numpy api: static PyObject * py_integrate(PyObject *self, PyObject *args){ ... std::vector<double> integral; cpp_function(integral); // this change integral npy_intp size = {integral.size()}; PyObject *out = PyArray_SimpleNewFromData(1, &size, NPY_DOUBLE, &(integral[0])); return out; } when I call it from python, if I do import matplotlib.pyplot as plt a = py_integrate(parameters) print a fig = plt.figure() ax = fig.add_subplot(111) ax.plot(a) print a the first print is ok, the values are correct, but when I plot a they are not, and in particular in the second print I see very strange values like 1E-308 1E-308 ... or 0 0 0 ... as an unitialized memory. I don't understand why the first print is ok.

  • How to print absolute line number in uncaught exception?

    - by DSblizzard
    When error occured Python prints something like this: Traceback (most recent call last): File "<stdin>", line 2, in <module> File "<stdin>", line 8, in m File "<stdin>", line 5, in exec_st File "<stdin>", line 9, in exec_assign File "<stdin>", line 48, in ref_by_id IndexError: list index out of range where 2, ... , 48 are relative line numbers which are not very convenient. How to print absolute line numbers in such error messages? EDIT: Maybe it's a dumb question, but answer will facilitate development a little. I'm printing text in several files. When done, press shortcut which runs python and copies contents of current file to console. Proposed solution forces to press excess keystrokes (Ctrl+S, Alt+Tab) and create additional files. I hope I have put it clear.

  • How to split up a long list using \n

    - by pypy
    Here is a long string that I convert to a list so I can manipulate it, and then join it back together. I am having some trouble being able to have an iterator go through the list and when the iterator reach, let us say every 5th object, it should insert a '\n' right there. Here is an example: string = "Hello my name is Josh I like pizza and python I need this string to be really really long" string = string.split() # do the magic here string = ' '.join(string) print(string) Output: Hello my name is Josh I like pizza and python I need this string to be really really long Any idea how i can achieve this? I tried using: for words in string: if words % 5 == 0: string.append('\n') but it doesn't work. What am I missing?

  • Why are closures broken within exec?

    - by Devin Jeanpierre
    In Python 2.6, >>> exec "print (lambda: a)()" in dict(a=2), {} 2 >>> exec "print (lambda: a)()" in globals(), {'a': 2} Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<string>", line 1, in <module> File "<string>", line 1, in <lambda> NameError: global name 'a' is not defined >>> exec "print (lambda: a).__closure__" in globals(), {'a': 2} None I expected it to print 2 twice, and then print a tuple with a single cell. It is the same situation in 3.1. What's going on?

  • Multiple Projects, Common Module

    - by EShull
    I have a library of common functions that I use in several different projects, which works fine on my local machine where I can just add the path to the library, but now that I've put several of my projects on GoogleCode, I'm not sure how to deal with the external library. Do I put copies of it in each project and try to keep them all synchronized with each other, or is there a better way?
