My laptop has been formatted and a new OS was installed, and since then I have gotten this error:
ImportError: No module named git
This refers to a Python code that simply imports git.
Location of git before my laptop was formatted: /usr/local/bin/git
Location of git after the laptop was formatted: /usr/bin/git
How / what do I change in my Python code to refer to the right path?
The git module is not the same thing as the git command line executable. They happen to have the same name and cover related tasks, but they are distinct software packages.
I'm going to assume that the git module your code is importing is the one provided by the GitPython project. You'll need to install that project, see their installation instructions:
# pip install gitpython
