Hi! Is there any benefits of using 'return' at the end of a python function if the function doesn't return any values? Thank you in advance!

There is an implicit return None at the end of every function or method. However, a simple return helps in readability.
When scanning code, a return is expected so it helps to see it. As the Zen of Python says “explicit is better than implicit”
The one exception is the __init__ method. It is never expected to return anything so a return is not used. The __init__ method operates on an existing instance referenced by self.
The following are functionally equivalent:
return None
return
# no return
Post back if you need more help. Good luck!!!
