git - How do you push to a gitlab repo using a gitlab-ci job?

Question

I am new to GitLab CI/CD jobs, but I'm trying to set up a Python script that when pushed to GitLab, triggers the CI/CD job to run it, and call an internal function that pushes to GitLab again provided that certain criteria are met. So, for example, suppose I have the following:

def hasFileInDirectory():
    # checks if the current directory has at least 1 other file in it
    if (1 or more files exist):
        print 'Great! You have enough files!';
    else:
        print 'Oh no! You need more files! Let me create one!';
        createFile('missingFile'+str(random.randint(0,1000000)+'.txt');
        os.system('git add -A');
        os.system('git commit -m "Automatically added new file..."');
        os.system('git push origin HEAD:master --force');

This function seems to run perfectly fine if I run it myself from the command line, however, it seems to not be able to run in the GitLab CI/CD job. The output I am getting is:

remote: You are not allowed to upload code.
fatal: unable to access 'https://gitlab-ci-token:xxxxx@gitlab.com/path_to/my_repository.git/': The requested URL returned error: 403

This error occurs when I call git push so I was wondering what I could do to fix this. I would really appreciate any help!
