3,094 Points"Recheck work" says something is wrong, but Preview shows what appears to be the desired result.
How do you move past the quiz?
import random
start = 5
def even_odd(num):
# If % 2 is 0, the number is even.
# Since 0 is falsey, we have to invert it with not.
return not num % 2
while start:
num = random.randint(1, 99)
if even_odd(num):
print("{} is even.".format(num))
else:
print("{} is odd.".format(num))
start -= 1

230,688 PointsThe challenges can be very picky!
In this case, the challenge is expecting messages formatted with the templates provided in the instructions. But your templates have punctuation added (a period).
Just remove the periods and you'll pass.
