Pushing local branch to remote branch - gitpython

问题

I created new repository in my Github. Using the gitpython library i'm able to get this repository. Then I create new branch, add new file, commit and try to push to the new branch.

Please check be code below:

import git
import random
import os

repo_name = 'test'
branch_name = 'feature4'

remote_repo_addr_git = 'git@repo:DevOps/z_sandbox1.git'

no = random.randint(0,1000)
repo = git.Repo.clone_from(remote_repo_addr_git, repo_name)
new_branch = repo.create_head(branch_name)
repo.head.set_reference(new_branch)
os.chdir(repo_name)
open("parasol" + str(no), "w+").write(str(no)) # this is added
print repo.active_branch
repo.git.add(A=True)
repo.git.commit(m='okej')
repo.git.push(u='origin feature4')

Everything working fine until last push method. I got this error:

stderr: 'fatal: 'origin feature4' does not appear to be a git repository fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.'

I'm able to run this method from command line and it's working fine:
