What is wrong with this code. Looks find to me and runs in workspaces like it should.

Not sure why I'm getting "Bummer! TypeError: can't multiply sequence by non-int of type 'str'"

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

Your code doesn't satisfy this condition:

squared("2") would return 4

Because you will be trying to multiply two strings together.

This is because when you call int(x), it doesn't actually change the value of x. It only returns the integer version of x.

If you want to modify the variable, you have to do this:

x = int(x)
