What is ActivePython?

ActivePython is ActiveState's binary distribution of Python. Builds for 
Windows, Mac OS X, Linux are made freely available. Solaris, HP-UX and 
AIX builds, and access to older versions are available in ActivePython 
Business, Enterprise and OEM editions:

ActivePython includes the Python core and the many core extensions: zlib 
and bzip2 for data compression, the Berkeley DB (bsddb) and SQLite 
(sqlite3) database libraries, OpenSSL bindings for HTTPS support, the 
Tix GUI widgets for Tkinter, ElementTree for XML processing, ctypes (on 
supported platforms) for low-level library access, and others. The 
Windows distribution ships with PyWin32 -- a suite of Windows tools 
developed by Mark Hammond, including bindings to the Win32 API and 
Windows COM.

ActivePython also includes a binary package manager for Python (PyPM) 
that can be used to install packages much easily. For example:

   C:\>pypm install mysql-python

   >>> import MySQLdb
