The script I've used seems to be correct when I run it through Workstation but "check work" doesn't think so, what am I missing? regards Dan
import random
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
if num % 2 == 0:
return True
else:
return False
start = 5
while start > 0:
number = random.randint(1,99)
even = even_odd(number)
if even == True:
print("{} is even.".format(number))
else:
print("{} is odd.".format(number))
start -= 1

On other thing I will point out though is that while it won't cause any errors most of the code in the even_odd function is redundant, the first line of code and the if...else statement does the exact same work, and once a function hits a return statement it stops the function and returns the value. Which means that any code in the function after the first return statement will never run, so you can remove the if...else statement entirely from the function and nothing would actually change.
