Pls help to figure out how to defined 'arg' to make my script work

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

def squared(arg):

    while True:
        try:
          arg = int()
          print(arg**2)
          return
        except ValueError:
          print(arg* len(arg))

Here's a few hints:

  • just define your function, don't call it yourself (the challenge does that for you)
  • you don't need a loop (because of the return's, it can't loop anyway)
  • you need to pass an argument to int that you want it to convert
  • you need to return the values, not print them

I'll bet you can get it now, but if you're still stuck...     <button' onclick='$("#spoiler").slideDown("slow");$(this).remove()'>Press to Reveal Spoiler</button> <div id='spoiler' style='display:none'>

:warning: SPOILER ALERT

squared.py 
def squared(arg):
    try:
        arg = int(arg)
        return arg ** 2
    except ValueError:
        return arg * len(arg)

</div>
