None vs Empty Return

The difference

These three functions all return None:

def f1():
    print("hi")
    # No return statement

def f2():
    print("hi")
    return  # Empty return

def f3():
    print("hi")
    return None  # Explicit None

All three do the same thing. Use whichever is clearest. Most people skip the return entirely for functions that don't need to return a value.
