Python: How Do I Display a List From PyQt4's QListWidgetItem()?

You may have to change self.listWidget.item() to PyQt4.QtGui.QListWidgetItem() for your situation.

Getting Py2exe to Work With Matplotlib for Python 2.5

I just started playing around with Matplotlib in Python 2.5.4. I love it so far. And, of course, I just had to make a Windows EXE file from a project I was working on. Nothing but crashes using Py2exe until I learned about glob.

The problem I was having was with the Matplotlib data files not being included/found when running the EXE. At the CMD prompt, I enter setup.py py2exe as usual.

The setup.py code is below:

# Used successfully in Python 2.5.4 for py2exe and matplotlib
from distutils.core import setup
import py2exe

import glob
 
opts = {'py2exe': {'includes': ['matplotlib.backends',
                                'matplotlib.backends.backend_qt4agg',
                                'matplotlib.figure', 'pylab', 'numpy',
                                'matplotlib.backends.backend_tkagg'],
                   'excludes': ['_gtkagg', '_tkagg', '_agg2', '_cairo', '_cocoaagg',
                                '_fltkagg', '_gtk', '_gtkcairo'],
                   'dll_excludes': ['libgdk-win32-2.0-0.dll', 'libgobject-2.0-0.dll']
                  }
        }

data_files = [(r'mpl-data', glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\*.*')),
                  (r'mpl-data', [r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\matplotlibrc']),
                  (r'mpl-data\images', glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\images\*.*')),
                  (r'mpl-data\fonts', glob.glob(r'C:\Python25\Lib\site-packages\matplotlib\mpl-data\fonts\*.*'))]

# for console program use "console = [{'script': '3d6_line_bar.py'}]"
# for windows program use "windows = [{'script': '3d6_line_bar.pyw'}]"
setup(windows = [{'script': '3d6_line_bar.pyw'}], options=opts, data_files=data_files)

Python Programming: Building Character

I recently posted a YouTube video showing how to quickly generate the beginnings of a role-playing character for Traveller, using Python 2.5.4.

The source code is below:

from random import randint

char_name = ['STR', 'DEX', 'END', 'INT', 'EDU', 'SOC', 'PSI']

char = [0,0,0,0,0,0,0]

for i in range(len(char_name)):
    char[i] = randint(1,6) + randint(1,6)
    
for i in range(len(char_name)):
    print '%s: %d' % (char_name[i], char[i])

I may do more such posts here in the future, now that I've recently learned how to properly post program code.

Python 3 is not Python

There was a time when Python was mature enough as a language for me to leave other languages I didn't care for and program strictly in Python. There was a time when Python programming was fresh and fun, yada yada. A time when print was a statement and not a function. A time when all the more interesting modules were written for Python, etc etc.

That time was Python 2.5.

Now Python has regulated itself to being updated just for the sake of being updated, making it less compatible or interesting for those that enjoyed the programming language enough to leave other languages.

Python 2.5 is for the computer programmer.

Python 3.x is for the software developer.

It's an entirely different mindset that Python 3 users come from. It's a job now, rather than a hobby. It's a corporate regulation rather than a computer artist's tool. Python 2.5 follows the Zen of Python, while Python 3 does not.

If I had my way, Python 3 would be renamed to something else. Because it is a different language, I mean, different development solution. And it doesn't run Python 2.5 code. Period.
