Python Naming Conventions

Give Feedback

Learn about Python naming conventions. In this lesson, you’ll see how to choose sensible names for Python objects such as variables, functions, modules and so on. You’ll also see what naming styles are compliant with PEP 8 and which one’s aren’t.

This was very clear, thank you! I have 1 question. You said classes should be named FirstLetterOfEachWordCapital, but what do you name a class being passed into a function (def somthing(MyClass): or def somthing(my_class):)?

For function and method arguments PEP 8 recommends using lowercase words connected by single underscores. For example:

class MyClass:
    pass

def something(my_class):
    # my_class is an instance of MyClass
    pass
