Reviewing your co-worker's code
Your co-worker is asking you to review some code that they've written and give them some tips on how to get it ready for production. You know that having a docstring is considered best practice for maintainable, reusable functions, so as a sanity check you decide to use this has_docstring() function on all of their functions.
def has_docstring(func):
"""Check to see if the function
`func` has a docstring.
Args:
func (callable): A function.
Returns:
bool
"""
return func.__doc__ is not None
