Question: Is there any official Python website documentation that describes how to install and execute multiple Python versions on a single Linux machine?
Answer: There is no official documentation on this topic available on the Python website. The recommendation is to rely on the operating system-specific guidelines for handling multiple Python versions.
For example, on Linux systems, you can simply install multiple Python versions without any conflicts, as each installation maintains its own libraries in dedicated directories. You can then use commands such as /usr/bin/python2.5 or /usr/bin/python2.6 to specify the desired Python version for execution. To set a default Python version, create a symbolic link from /usr/bin/python to the preferred version, such as:
ln -s /usr/bin/python2.6 /usr/bin/python
Compiling and Installing Manually:
If you prefer to compile and install Python versions manually, you can refer to the guidelines outlined in the Python source code's readme file:
For example, if you want to install Python versions 2.5, 2.6, and 3.0 with 2.6 designated as the primary version, you would execute these commands:
