質問 5：
Fix the missing return statement in this function that should return whether a number is even.
def is_even(number):
if number % 2 == 0:
True
else:
False
正解：
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The expression number % 2 == 0 checks whether the number is even.
Step 2: The original code writes True and False, but it does not return them.
Step 3: A function must use the return statement to send a value back to the caller.
Correct code:
def is_even(number):
if number % 2 == 0:
return True
else:
return False
Simplified correct code:
def is_even(number):
return number % 2 == 0
Example:
print(is_even(4))
print(is_even(7))
Output:
True
False
