I am looking to get only the diff of a file changed from a git repo. Right now, I am using gitpython to actually get the commit objects and the files of git changes, but I want to do a dependency analysis on only the parts of the file changed. Is there any way to get the git diff from git python? Or am I going to have to compare each of the files by reading line by line?

Git does not store the diffs, as you have noticed. Given two blobs (before and after a change), you can use Python's difflib module to compare the data.

The repo I am working on only has one master branch. If I am trying to get two blobs, how do i get a second one to compare the before change? –  user1816561 Nov 19 at 16:15
 
Sorry, just another question. So beyond trying to get both the a blob and b blob and understanding what those are, will those blobs actually give me the content of the file changed? –  user1816561 Nov 19 at 17:00
