Hi Dennis,

This is quite a tricky challenge. Please see the code I used below to pass this challenge:

def squared(num):
    try:
        convertedNumber = int(num)  # Try to convert your argument to an integer and store it in variable
        return convertedNumber ** 2    # return variable squared (**2)
    except ValueError:                        # except the Value Error you could receive
        return num * len(num)             # return the num argument multiplied by its length

Hope this helps! Happy Coding!!!

In your try block you need to take into account that the argument passed in might be a string. Remember, there is a function you can use to cast a string into an integer. You should use that function inside of the try block with the variable num as it's argument.

The second part you will need to do is to use an except clause which will "activate" if the function in the try clause throws an error (check to see what kind of error the function you called in the try block will throw) which should be included in the except condition. Inside the except clause, multiply the num variable by the length of the variable.

def squared(num):
    try:
        return [some function](num) ** 2
    except [some kind of error]:
        return num * [some other function](num)
