Output None in function

Question

why here the output of my_func is None? I assign an integer to x then I have an expression in local scope.

Def my_func():
       x=4
       x**2
Print(my_func())

Output: None

Answer 1

If you don't write any return statement then the function returns None So you return the value you want to print or else print it in the function itself or else use lambda function as follows

print((lambda x: x**2)(4))

So simple right!! Have a look at OOPS concepts and lambda functions of Python to know more

Thank You!
