Simple example on how to use web APIs in Python3.

do_get_git_public_repo_name.py

import requests # importing libraries for working with HTTP requests
import json             

api_url_base = 'https://api.github.com/' # string that starts off every URL in the GitHub API
#response = requests.get(api_url_base)
#print(response.headers)

headers = {'Content-Type': 'application/json',
            'Accept': 'application/vnd.github.v3+json'
            }

def get_repos(username):
    '''
    This function accepts a username as its argument
    This function will get the list of github repos
    '''

    api_url = '{}users/{}/repos'.format(api_url_base, username)
    print(api_url)
    response = requests.get(api_url, headers=headers)
    #data = response.json()
    #print(data.name)


    # code should always check the HTTP status code for any response before trying to do anything with it. 
    # notherwise we find ourself wasting time troubleshooting with incomplete information.

    if response.status_code == 200:
        # Getting JSON from an API request
        # Get the response data as a object. 
            
        data = response.json()

        #return (response.content) # in bytes format
            
        print(len(data)) #  find number of repos

        return ([data[x]['name'] for x in range(len(data))]) # return the list of the name of the repositories of the relevant user
       #return ([(data[x]['name'],data[x]['description']) for x in range(len(data))])  # return the list of the tuple including name and description of the repositories of the relevant user
       
    else:
        print('[!] HTTP {0} calling [{1}]'.format(response.status_code, api_url))
        return None
