I tried giving it one of the prompts from copilot.github.com: def strip_suffix(filename): """ Removes the suffix from a filename """ return filename[:filename.rfind('.')] def test_strip_suffix(): It completed the test function like this: # test stripping of a suffix a = strip_suffix("I_am_file.txt") assert a == "I_am_file" Compare this with GitHub Copilot, which gives: """ Tests for the strip_suffix function """ assert strip_suffix('notes.txt') == 'notes' assert strip_suffix('notes.txt.gz') == 'notes.txt' GPT-J also gave a bunch of explanation on how to use the generated code: So this goes in a file called my_file.py and when you run python3.4 -m my_file.strip_suffix you should get the following output C:\Users\user\Desktop>python3.4 -m my_file.strip_suffix 'strip_suffix' C:\Users\user\Desktop> So the strip_suffix function which strips the suffix from a filename is called as part of a larger code that uses some functions from the file. To tell Python what functions are available in a file you just need to put #-comment characters on the first line and then the functions that you want to use, and the first line will be taken as the function documentation: #-*- coding: utf-8 -*- #comment def func_one(): ''' Documentation for function one. ''' print("This is the doc for func_one
