Tested in python ide with correct output for all cases such as 2, "2", and "two."

treehouse says "squared didn't return the right answer. I got the right answer for all other cases in IDLE. I don't understand why its not producing the correct output.

squared.py 
# EXAMPLES
# squared(5) would return 25
# squared("2") would return 4
# squared("tim") would return "timtimtim"
def squared(arg):
    try:
        return print(int(arg) ** 2)
    except:
        return print(arg * len(arg))

The problem here is that you're wrapping the return values in print statements. You're printing out the correct answer, but the print function itself always returns None, so your function will only ever return None. If you remove the print statements, I think it'll work fine. That being said, it's considered bad form in Python to just generally except everything. In your case, I think you want to except ValueError in case the input can't be converted to an int
