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.

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

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

Hi Dehzi,

In your code you check if num == int(num). Which will be true if it's already an int. But if it's a string it's going to see if the string is equal to it's value converted to a string. e.g. if I pass in "5" this is what the statement will look like

if "5" == 5:
    do stuff

but string "5" is not equal to int 5.

after the try statement assign num to a variable after trying to convert it to an int. if it can be converted to an int it'll be true and If it's already an int it'll be true.

Good luck!
