Instruction
Good. Functions can also return some values. For instance, when you execute isnumeric(), the function returns either True or False.
def factorial(number):
score = 1
while number > 1:
score = score * number
number = number - 1
return score
The program above takes an input number and returns its factorial (e.g., for number = 4, the function will return 4*3*2*1 = 24). The return keyword terminates the function and makes it return the value specified after the return keyword to the caller.
Exercise
Write a function named return_bigger(a, b) that takes two numbers and returns the bigger one. If the numbers are equal, return 0.
Stuck? Here's a hint!
Use a simple if statement:
if a > b: return ... elif b > a: return ... else: return 0
