GitPython can be used to clone a Git repo. However, I would not use GitPython because https://github.com/gitpython-developers/GitPython says:

This project is in maintenance mode, which means that

• …there will be no feature development, unless these are contributed
• …there will be no bug fixes, unless they are relevant to the safety of users, or contributed
• …issues will be responded to with waiting times of up to a month

For this reason, I would instead use subprocess to clone a Git repo. Check out my article FreeKB - Python (Scripting) - Native operating system commands.
