PyOpenGL and PyOpenGL-accelerate 3.0.1 - latest version

First , the major error is this:

I try fix this with ... NetFx20SP2_x86.exe, not working.
I use google to donload the dll file. Is not correct way , but this fix error.
I use this PyOpenGL-3.0.1.zip to install OpenGL module under Python 2.6.2 ...
Just use this :

python setup.py install

But you can not use python on command line, because you need to add on enviroment vars...
Just try something like this...

C:\>set PATH=C:\Python26;%PATH%

To see the result , just use:

C:\path

You can test the OpenGL modules...

>>> import OpenGL
>>> import OpenGL_accelerate
>>> help(OpenGL_accelerate)

Logging documentation for Python 2.7 reorganised like Python 3

First , what is logging module ?

This module defines functions and classes which implement a flexible event logging system for applications and libraries.

The organisation is now as follows:

• http://docs.python.org/library/logging – reference documentation for the logging module
• http://docs.python.org/library/logging.config - reference documentation for the logging.config module
• http://docs.python.org/library/logging.handlers - reference documentation for the logging.handlers module
• http://docs.python.org/howto/logging – basic and advanced logging tutorials
• http://docs.python.org/howto/logging-cookbook – how to use logging in different scenarios

The best way to understand this module is to see the tutorials...

Using modules in Python 3.2

Python is quite known and appreciated.
Today I saw an article "What's your favorite programming language?" LinuxWeek proncetaj of a 26% (1074 votes) ...
In python "module" which is actually a library.
Using it is simple: import "module name"
See example below:

import os

There are many modules in the Python language.
For example I chose an example of how to display modules that are installed. Open the python command line and run the examples below:

C:\Python32>python
Python 3.2 (r32:88445, Feb 20 2011, 21:29:02) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

PyGUI 2.4 is available from

PyGUI is a cross-platform GUI toolkit designed to be lightweight and have a highly Pythonic API.
It's works with Python 3 on MacOSX and Windows.
You use the OpenGL facilities but you will need PyOpenGL and GtkGLExt and PyGtkGLExt.
Official site is here.
In this image you can see some controls created with PyGUI.

Python Tools for Visual Studio

I just read that python will be placed in the tools in Visual Studio.
This can only be good news for the python community.
More about this here.

The discovery of an ancient ancestors linux ...

Who says penguins are weak?
Linux is a good system if it is used by smart people.
Since ancient times people are born with penguins.
It seems that dinosaurs could not survive, but the Penguins have managed well.
They became smaller but everyone loves them.
Whether they are small and fast as gentoo, or slower ... we are glad that we have no windows open.

IronPython released on 12 and updated on 13 march.

What is it?
IronPython is an implementation of the Python programming language and is running under .NET and Silverlight.

How does it work?
When you run a .NET program written in a language such as C# or VB.NET, your code gets compiled to Intermediate Language (IL) code.
IronPython contains the code and classes for IronPython itself, including the IronPython interpreter. When you run the IronPython interpreter, you are running the IL code for IronPython itself.
More simplistic, the classes you create in your Python code are created dynamically at runtime.

What's New?
This release numerous bug fixes, also includes a IronPython Tools for Visual Studio, support for extension methods and more...
You can see more on official site.

Just a simple python weather script.

Sometimes we need simple solutions. An example is displaying data on a computer screen using conky. under Linux.
Another example is the display of data without using the browser.
Whether you use Windows or Linux python scripts come to help. Here's a simple example written in python that can display weather data.

import urllib
from xml.dom import minidom

wurl = 'http://xml.weather.yahoo.com/forecastrss?p=%s'
wser = 'http://xml.weather.yahoo.com/ns/rss/1.0'

def weather_for_zip(zip_code):
    url = wurl % zip_code +'&u=c'
    dom = minidom.parse(urllib.urlopen(url))
    forecasts = []
    for node in dom.getElementsByTagNameNS(wser, 'forecast'):
        forecasts.append({
            'date': node.getAttribute('date'),
            'low': node.getAttribute('low'),
            'high': node.getAttribute('high'),
            'condition': node.getAttribute('text')
        })
    ycondition = dom.getElementsByTagNameNS(wser, 'condition')[0]
    return {
        'current_condition': ycondition.getAttribute('text'),
        'current_temp': ycondition.getAttribute('temp'),
        'forecasts': forecasts ,
        'title': dom.getElementsByTagName('title')[0].firstChild.data
    }
def main():
    a=weather_for_zip("ROXX0003")
    print '=================================='
    print '|',a['title'],'|'
    print '=================================='
    print '|current condition=',a['current_condition']
    print '|current temp     =',a['current_temp']
    print '=================================='
    print '|  today     =',a['forecasts'][0]['date']
    print '|  hight     =',a['forecasts'][0]['high']
    print '|  low       =',a['forecasts'][0]['low']
    print '|  condition =',a['forecasts'][0]['condition']
    print '=================================='
    print '|  tomorrow  =',a['forecasts'][1]['date']
    print '|  hight     =',a['forecasts'][1]['high']
    print '|  low       =',a['forecasts'][1]['low']
    print '|  condition =',a['forecasts'][1]['condition']
    print '=================================='

main()

Here is the result of script execution:

>>> 
==================================
| Yahoo! Weather - Bucharest, RO |
==================================
|current condition= Light Snow
|current temp     = -3
==================================
|  today     = 23 Feb 2011
|  hight     = 0
|  low       = -5
|  condition = Light Snow
==================================
|  tomorrow  = 24 Feb 2011
|  hight     = 0
|  low       = -4
|  condition = Mostly Cloudy

Read feed from sites.

Is a simple example for reading some feed.
I use two functions , first read url and secondary extract data.
This is the code source:

from xml.dom import minidom as dom
import urllib

def fetchPage(url):
    a = urllib.urlopen(url)
    return ''.join(a.readlines())


def extract(page):
    a = dom.parseString(page)
    item2 = a.getElementsByTagName('SendingDate')[0].firstChild.wholeText
    print "DATA ",item2
    item = a.getElementsByTagName('Cube')
    for i in item:
        if i.hasChildNodes() == True:
            e = i.getElementsByTagName('Rate')[10].firstChild.wholeText
            d = i.getElementsByTagName('Rate')[26].firstChild.wholeText
            print "EURO  ",e
            print "DOLAR ",d

if __name__=='__main__':
    page = fetchPage("http://www.bnro.ro/nbrfxrates.xml")

    extract(page)

Result is :

DATA  2011-02-03
EURO   4.2609
DOLAR  3.0921

This is all...

Python - calendar

Two simple example about calendar python module.
Show calendar 04 - 2011 :

>>> import calendar
>>> tc = calendar.TextCalendar(calendar.SUNDAY)
>>> print tc.formatmonth(2011,04)
     April 2011
Su Mo Tu We Th Fr Sa
                1  2
 3  4  5  6  7  8  9
10 11 12 13 14 15 16
17 18 19 20 21 22 23
24 25 26 27 28 29 30

>>>

Show calendar in HTML format :

>>> import calendar
>>> hc = calendar.HTMLCalendar(calendar.SUNDAY)
>>> print hc.formatmonth(2011,04)
;

The result is a HTML table with the calendar.
This is all .

Random module - another example

Random module is a module used in everyday programming.
Even if it is not used in the final software, he helps us to test various types of random data.
We present you a simple example - play with cards.
We chose a list of cards of one color for not having a large number of elements.
We exemplify the use of random module by analogy with a game of cards.
That it means: shuffle cards , select just one from cards and a choice selection of a defined number of cards.
Below you see the code used as an example.

>>> import random
>>> choice=random.choice
>>> shuffle=random.shuffle
>>> for i in range (9):
...     print choice(cards)
... 
Q
K
10
Q
2
2
10
K
6
>>> shuffle(cards)
>>> cards
[4, 7, 10, 'J', 3, 'Q', 6, 2, 'K', 9, 'A', 8, 5]
>>> sample=random.sample
>>> sample(cards,5)
[8, 'J', 2, 'Q', 10]
>>> sample(cards,5)
['A', 9, 4, 'K', 'Q']
>>> 

The random module docs
