Square(int) function with "try""except" works in workspace, but wont pass the code challenge ?!

This code challenge is asking me to make function with 1 argument. and this should happen: 1) if its an integer, return it squared 2) if not (a string) then multiply that string with its length

This is the code I ran and im getting " 'squared' didn't return the correct results ". I checked the code on workspace using the examples at the top of the code and it works as intended. Am I missing something here ?

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

def squared(arg):
    try:
        int(arg)
        return arg*arg
    except:
        return arg*len(arg)

for example you wrote in arg '5'. It could be int('5'), right? But you can't multiply that string '5'*'5', because you didn't save the restult in arg variable. But you can first to int it and then mulptiply that, ok?

I think it's because you didn't name the exception you were trying to throw...

except ValueError:

I checked that, It says " TypeError: Can't multiply sequence by non-int type 'str' "

I see, In your code, the int() is embedded in the return. I editted my code from:

" int(arg) return arg**2"

to

" return int(arg)**2"

And it got solved. Interesting..
