Tell us what’s happening:
Describe your issue in detail here.
I am currently stuck on the following subtasks:

When the secret number is guessed, your script should print You guessed it in <number_of_guesses> tries. The secret number was <secret_number>. Nice job!
While doing my own tests I am getting the desired result

Your code so far

NUM=0

Were you able to get this resolved @gaurav_t? I made a database and used your code - it failed the first few times I ran the tests, but after I completed all the other user stories and ran the tests again, it passed. I don’t think it was from me finishing the other user stories, but I’m not sure. I would give that a try. I am looking into the tests to see if there’s an issue.
