I know this comment was left a while ago but the reason is because using the program is taking to long when using the while loop and random module.

The random module isn't great to use in this case it's not the most reliable. You're basically throwing randoms so may get the same results a few times. The while parameters is a little tricky as well.

There is an issue with this kata. I tested on my code editor and it was right. The Kata is not recognizing my answer as correct.
