I am trying o grasp gitpython module, 

hcommit = repo.head.commit
tdiff = hcommit.diff('HEAD~1')

but tdiff = hcommit.diff('HEAD^ HEAD') doesn't work !! neither does ('HEAD~ HEAD').,

I am trying to get the diff output !

I admit to never having used the gitpython code, but it seems obvious that if hcommit is repo.head.commit, it's bound to that particular commit, and thus hcommit.diff means "diff that particular commit, against something else". To get diffs of two arbitrary commits, you'd have to choose some other starting-point. –  torek Feb 25 at 17:39

I figured out how to get the git diff using gitPython.

import git
repo = git.Repo("path/of/repo/")

# the below gives us all commits
repo.commits()

# take the first and last commit

a_commit = repo.commits()[0]
b_commit = repo.commits()[1]

# now get the diff
repo.diff(a_commit,b_commit)

Voila !!!
