Explanation of Returns , in python


please can someone explain to me in simple terms ; Returns. in the python course



the examples in the lessons are pretty good:

def divide_by_four(input_number):
    return input_number/4

result = divide_by_four(16)
# result now holds 4
print("16 divided by 4 is " + str(result) + "!")

return is literally what is says, handing back a value to the function call
