How Can I Run Multiple Python Versions Simultaneously on Windows?

Using Multiple Python Versions on Windows

Need to run different Python versions simultaneously on Windows, but not sure how? Here's the answer:

Run Python Instances as Specified

Windows users with multiple Python versions can easily specify which one to execute. By default, typing "python" in the command line will launch the executable that's first in the %PATH% environment variable.

Explicitly Calling Python

To avoid this default behavior, explicitly call the desired Python executable. For example, to run Python 2.5, type "c:python2.5python.exe."

Creating Shortcuts

Alternatively, create shortcuts to the python.exe files in the appropriate directories, naming them differently (e.g., "python25" and "python26"). This enables you to simply type the shortcut name on the command line (e.g., "python25").
