Python 3.0 Final Released

Python 3.0 (a.k.a. “Python 3000″ or “Py3k”) is a new version of the language that is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed. Also, the standard library has been reorganized in a few prominent places.

Google App Engine

Downloads (http://code.google.com/appengine/downloads.html)

Google App Engine use Django, webob, yaml.

You need Python (http://www.python.org) (Python 2.5)

The configuration file app.yaml

There are two main Python scripts:

• dev_appserver.py: the development web server
• appcfg.py: for uploading your app to App Engine

Using Windows ? Don’t Kill Yourself

Supose you are Linux user and you have a Windows system.

Alternatives: Cygwin, Mingw or Colinux

You need some (or all) of this interpreters:

Perl, PHP, Python and Ruby

Modify the %PATH%

Example you have a bin dir, on C:\ to include the executables on the %PATH% do this:

set PATH=%PATH%;C:\bin\

On Windows Vista, you can use your mouse:

computer > properties > Advances system settings > (continue) > Advanced > Enviroment Variables > System Variables > Path (edit)

Example run Kompozer on cmd.exe but no modify %PATH%

: kompozer.bat save on %WINDIR%
@"C:\Program Files\Kompozer\kompozer.exe"

Doble click on your scripts to run:

: Perl Scripts
 assoc .pl=Perl.File
 ftype Perl.File=C:\strawberry\perl\bin\perl.exe "%1" %*
 set PATHEXT=%PATHEXT%;.pl
: Python Scripts
 assoc .py=Python.File
 ftype Python.File=C:\Python26\python.exe "%1" %*
 set PATHEXT=%PATHEXT%;.py

Note:

On Windows Vista you need run cmd.exe as Administrator don’t work as normal user

Apache, PHP and MySQL ?

XAMPP and Server2Go

Notes:

XAMPP: simple, quick and easy install.

Server2Go: is great to make CD demo of a Web Application.

Using Perl or Python as CGI on Windows ?

Using Python 2.6

#!\python26\python.exe

Using Strawberry Perl:

#!\strawberry\perl\bin\perl.exe

Now your script works on http://localhost/cgi-bin/script.cgi

PunBB + Python = PynBB (Linked)

I say:

Is a great honor to me, you linked my python script (PynBB) to the wiki of PunBB

I will continue learing python and punbb source code to give more options to this script

Thanks.

PunBB + Python = PynBB

I made this Python script interface of PunBB forums

Download this script: [pynbb.py]

Edit this vars:

HOST = ""	# PunBB WebSite without http:// and slashes
PATH = ""	# Example: domain.com/forum PATH ="/forum"
USER = ""	# Your Username (Important: case sensitive)
PASS = ""	# Your Password
 
###################################################################
# END OF EDITABLE OPTIONS #

Run:
