If you want to do git diff on a file between two commits this is the way to do it:

import git

repo = git.Repo()
path_to_a_file = "diff_this_file_across_commits.txt"

commits_touching_path = list(repo.iter_commits(paths=path))

print repo.git.diff(commits_touching_path[0], commits_touching_path[1], path_to_a_file)

This will show you the differences between two latest commits that were done to the file you specify.

Hope this helped.
