Can anyone explain me what is wrong ? :) Thank you

```
import random
start = 5
while True:
num = random.randint(1, 99)
def even_odd(num):
return not num % 2
print("{} is even".format(num))
else:
print("{} is odd")
start -= 1
```

Python Python Basics Letter Game App Even or Odd Loop

issue on 3rd part of challenge, not sure how to decrement start, also not 100 if my code is correct
Alright, last step but it's a big one.
Make a while loop that runs until start is falsey.
Inside the loop, use random.randint(1, 99) to get a random number between 1 and 99.
If that random number is even (use even_odd to find out), print "{} is even", putting the random number in the hole. Otherwise, print "{} is odd", again using the random number.
Finally, decrement start by 1.
I know it's a lot, but I know you can do it!
import random
start = 5
def even_odd(n_num):
while start == True:
n_num = random.randint(1,99)
new_num = n_num % 2
if new_num != 0:
print("{} is odd".format(n_num))
else:
print("{} is even".format(n_num))
#return not % 2 ----- not sure what to do with this pre-inserted code
else:
start -1
#while loop >>>
#make a random int call 1-99 >>>
#print if number is even/even_odd >>>
#decrement start by 1
even_odd(n_num)

The intent of the challenge is to used the function even_odd in a while loop:
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
# Make a while loop that runs until start is falsey.
while start:
# Inside the loop, use random.randint(1, 99) to get a random number between 1 and 99.
n_num = random.randint(1,99)
if even_odd(n_num):
# If that random number is even (use even_odd to find out)...
# print "{} is even", putting the random number in the hole.
print("{} is even".format(n_num))
else:
# Otherwise, print "{} is odd", again using the random number.
print("{} is odd".format(n_num))
# Finally, decrement start by 1.
start -= 1
```

Courses Plus Student 7,028 PointsStill not working. Oops! It looks like Task 1 is no longer passing.

###### Josh Keenan

19,649 PointsOh yeah the loop should be in the function not the other way around,

###### Emmanuel Koranteng

21,488 PointsChange while condition to `while start != False:`

###### Josh Keenan

19,649 PointsIn this case this is wrong as the loop won't run still, we do until start is equal to 0 as 0 can also mean false.
