Python program that gets basic information on a Github user
Just a note:
instead of using string.split() to check for spaces, you can directly check with in.

From:


if len(username.split()) != 1:
        print('Github usernames must be one word in length! Exiting!')
        return



To:

if ' ' in username:
        print('Github usernames cannot contain spaces! Exiting!')
        return


Also, instead of multiple print statements, you can use multiline strings: """...""" or '''...'''.

From:


print(f'The following information was found on user: {username}',
      end='\n\n')
print(f'Name: {responses_json["name"]}')
print(f'Bio: {responses_json["bio"]}')
print(f'Followers: {responses_json["followers"]}')
print(f'Following: {responses_json["following"]}')



To:

print(f'''
The following information was found on user: {username}

Name: {responses_json["name"]}
Bio: {responses_json["bio"]}
Followers: {responses_json["followers"]}
Following: {responses_json["following"]}''')
