I really need someone to explain the return character in a function very simple and understandable

Answer 1

Oumar Amidu Ndongo , here is short sample with some comments:

def add(num1, num2):
sum_ = num1 + num2
return sum_

inp1 = 3
inp2 = 5

res = add(inp1, inp2)
print(res)

# or in short:
print(add(inp1, inp2))

- you have 2 variables inp1 and inp 2, each of them holds an integer number
- you also have a function add(), that can take 2 arguments
- you call the function with add(inp1, inp2), so you pass the 2 arguments to this function.
- the 2 values passed to the function are now in the variables num1 and num2
- the function adds the 2 numbers and stores the result in variable sum_
- last step in the function is to return the variable sum_ back to the caller and is stored there in a variable called res
- finally the variable res will be printed and shows 8 as result.

Answer 2

Very simple:
return returns what you posted after return, in... right side, ....of the return statement. --left side-- return --right side-- <=here
Understandable:
function can return something and can do not return.
it depends have you placed return in function or not.

def whoho():
return "spam and eggs"
def hohoo():
print(spam eggs")
