Missing function docstring
Missing function or method docstring used when a function or method has no docstring. Some special methods like init, protected, private functions, setters and deleters do not require a docstring (learn more from testscases). It's a good practice to describe what a function does for other programmers.
Noncompliant Code:
Copy
def foo():
pass
Compliant Code:
Copy
def foo():
"""A dummy docstring."""
