How to Get And List All files from a Github Repository

I am trying to list all files from a Github repository.

def listFiles(self, filepath):
    git = githubHandler(GH_USERNAME, GH_PASSWORD)
    gh, repo, branch = git.connect_to_github()        
    tree = branch.commit.commit.tree.recurse()
    print repo.blob
    print branch

So far I can only output the repo branch and name. Any ideas?

So this is how I solved it after struggling for a while:

def list_filenames(self, filepath):
    git = githubHandler(GH_USERNAME, GH_PASSWORD)
    gh, repo, branch = git.connect_to_github()        
    tree = branch.commit.commit.tree.recurse()
    for filename in tree.tree: 
        print("[*] Found file {0}".format(filename.path)) 
        print filename.path
    return None
