Python Python Basics (2015) Number Game App Squared

How do I solve it

I need to 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, return the argument multiplied by its length. how can I convert a string to an integer

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

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

You're very close. int(num) will check if the conversion is possible but it doesn't retain the converted value. Either, update num with assigned conversion:

        int = int(num)
        return num * num

Or convert in the `return statement:

        return int(num) * int(num)
