Confusing, Please help

I'm confuse in this challenge question, can anyone help? The question is {"This challenge is similar to an earlier one. Remember, though, I want you to practice! You'll probably want to use try and except on this one. You might have to not use the else block, though. Write a function named squared that takes a single argument. If the argument can be converted into an integer, convert it and return the square of the number (num ** 2 or num * num). If the argument cannot be turned into an integer (maybe it's a string of non-numbers?), return the argument multiplied by its length. Look in the file for examples"} I don't know the mistake in my code if find the mistake, please answer

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

Your code is close to correct, but there are two issue with your last line of code.

The challenge asks you to return the argument multiplied by it's length, in your code you do not actually multiply it by using the multiplication operator (*), you use (**) which is a power to operator. In addition to that you are trying to multiply the length of the argument by 2, instead of multiplying the length with the argument itself, which is what the challenge asked for.

Fixing those two issues produces this code:

def squared(num):
    try: 
        return int(num) ** 2
    except: 
        return len(num) * num

which will allow you to pass the challenge.

Thanks a lot, I was trying to figure this out from a long time
