1.2. Python on Windows

On Windows, you have a couple choices for installing Python.

ActiveState makes a Windows installer for Python called ActivePython, which includes a complete version of Python, an IDE with a Python-aware code editor, plus some Windows extensions for Python that allow complete access to Windows-specific services, APIs, and the Windows Registry.

ActivePython is freely downloadable, although it is not open source. It is the IDE I used to learn Python, and I recommend you try it unless you have a specific reason not to. One such reason might be that ActiveState is generally several months behind in updating their ActivePython installer when new version of Python are released. If you absolutely need the latest version of Python and ActivePython is still a version behind as you read this, you'll want to use the second option for installing Python on Windows.

The second option is the “official” Python installer, distributed by the people who develop Python itself. It is freely downloadable and open source, and it is always current with the latest version of Python.

Procedure 1.1. Option 1: Installing ActivePython

Here is the procedure for installing ActivePython:

Download ActivePython from http://www.activestate.com/Products/ActivePython/.
If you are using Windows 95, Windows 98, or Windows ME, you will also need to download and install Windows Installer 2.0 before installing ActivePython.
Double-click the installer, ActivePython-2.2.2-224-win32-ix86.msi.
Step through the installer program.
If space is tight, you can do a custom installation and deselect the documentation, but I don't recommend this unless you absolutely can't spare the 14MB.
After the installation is complete, close the installer and choose Start->Programs->ActiveState ActivePython 2.2->PythonWin IDE. You'll see something like the following:

PythonWin 2.2.2 (#37, Nov 26 2002, 10:24:37) [MSC 32 bit (Intel)] on win32.

Procedure 1.2. Option 2: Installing Python from Python.org

Download the latest Python Windows installer by going to http://www.python.org/ftp/python/ and selecting the highest version number listed, then downloading the .exe installer.
Double-click the installer, Python-2.xxx.yyy.exe. The name will depend on the version of Python available when you read this.
Step through the installer program.
If disk space is tight, you can deselect the HTMLHelp file, the utility scripts (Tools/), and/or the test suite (Lib/test/).
If you do not have administrative rights on your machine, you can select Advanced Options, then choose Non-Admin Install. This just affects where Registry entries and Start menu shortcuts are created.
After the installation is complete, close the installer and select Start->Programs->Python 2.3->IDLE (Python GUI). You'll see something like the following:

Python 2.3.2 (#49, Oct  2 2003, 20:02:00) [MSC v.1200 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
