The error message I am getting is "Wrong number of prints". Any idea what he problem could be?
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 == 5:
asd = random.randint(1, 99)
if even_odd(asd):
print("{} is even".format(asd))
else:
print("{} is odd".format(asd))
start -= 1

The problem lies with the condition you set for the while loop. You have while start == 5
which will run the loop only once, as the decrement will make the next iteration equal to 4. Other than that, your code is all correct.
The challenge want the loop to run all 5 times, so the condition you need will be > 0
. This way with each loop the value will decrement by one until the start
variable is zero.
Below is the corrected code. I hope it'll make sense. :)
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 > 0:
asd = random.randint(1, 99)
if even_odd(asd):
print("{} is even".format(asd))
else:
print("{} is odd".format(asd))
start -= 1
Keep Coding!
