Im using GitPython to clone a master branch and do a checkout of a feature branch, I do my local updates, commit and push back to git. The code snippet looks like below,

Note : my branch name is feature/pythontest

def git_clone():repo = Repo.clone_from(<git-repo>, <local-repo>)repo.git.checkout("-b", "feature/pythontest")# I have done with file updates repo.git.add(update=True)repo.index.commit("commit")origin = repo.remote(name="origin")origin.push()

When I execute the script, I get the below error,

To push the current branch and set the remote as upstream, use
git push --set-upstream origin feature/pythontest

For pushing new branches you need to run git push --set-upstream origin branch_name you can read on --set-upstream in git documentation https://git-scm.com/docs/git-push This should do the work for gitpython:

def git_clone():branch_name = "feature/pythontest"repo = Repo.clone_from(<git-repo>, <local-repo>)repo.git.checkout("-b", branch_name)repo.git.add(repo.working_dir)commit_output = repo.git.commit(m="Commit msg")push_output = repo.git.push('--set-upstream', repo.remote().name, branch_name)

Hope this helps!
