Tried this as a if/else, and it works, but I'm missing something when I use try/except.

Thank you!

squared.py
# EXAMPLES
# squared(5) would return 25
# squared("2") would return 4
# squared("tim") would return "timtimtim"

def squared(num):
    if type(num) != int:
        num = int(num)
        try:
            return(num **2)
        except:
            return(num * len(num))

Hi there! You're so close here! And because you're so close, I'm going to see if you can get the solution with a few hints. First, you can remove the if part altogether. All you'll need here is a try and except. And what exactly are we trying? We're trying to convert the input into an int. You need to be testing first if the number can be turned into an int and then squared and return that result. However, if it fails, it should go to the except ValueError block, where your code is currently correct :smiley: Hope this helps! :sparkles:

Jennifer, you're the best! You weren't kidding, I was right there already, except I stacked the if above the plain old "try". Probably because I started out that way, and am more used to if/else in exercises so far, I just added more layers than I needed. Lesson learned. Thanks for you help and thanks for the rapid response.
