How to execute 'ls-remote --heads origin master' in python?

Question

I have some basic python script inside my git repo. First I test some git command in my repo:

$ git ls-remote --heads origin master
a5dd03655381fcxxxx4e759ceba7aeb6456 refs/heads/master

Now I want to execute the same command in Python:

 if subprocess.call(["git", "ls-remote --heads origin master"]):
        print("OK")
    else:
        print("Not OK")

The output is:

git: 'ls-remote --heads origin master' is not a git command. See 'git --help'.
OK

What am I missing? When I just execute ls-remote in my python script it works:

a5dd03655381fcxxxx4e759ceba7aeb6456 HEAD
a5dd03655381fcxxxx4e759ceba7aeb6456 refs/heads/master

(I know the if statement is 'wrong/useless now').

Answer 1

you need to put every parameter in a separate item in the list.

import subprocess

if subprocess.call(["git", "ls-remote", "--heads", "origin", "master"]):
    print("OK")
else:
    print("Not OK")
