How Can I Run Specific Python Versions on Windows When Multiple Are Installed?

Running Multiple Python Versions on Windows

Problem:

You have installed multiple versions of Python on your Windows machine and want to specify which version to run for different projects.

Solution:

Instead of using the generic command "python," you can explicitly specify the path to the desired Python executable. Under Windows, this involves navigating to the Python installation directory and running the following command:

[Path to Python Installation]\python.exe

For example, if you have Python 2.6 installed in "C:Python2.6," you would run the following command:

C:\Python.6\python.exe

Alternative Solutions:

• Create shortcuts to the specific Python executables (e.g., "python25.exe" and "python26.exe") and run them from the command line.
• Use a command line alias to assign different names to the Python versions. For example, you could add the following line to your .profile or .bashrc file:

alias python25='C:\Python.5\python.exe'
alias python26='C:\Python.6\python.exe'
