Trial.py Task 3. Add a try block.

Hi Guys,

I already looked up some answers, but it is still not working. The System tells me that Task1 is no longer passing. I reloaded the challenge several times.

Thx in advance

Kris

trial.py 
def add(arg1, arg2):
    try:
        return float(arg1) + float(arg2)
    except ErrorValue:
            return none
        else:
    try:
        arg1 = float(arg1)
        arg2 = float(arg2)
    except ValueError:
        return none
    else:
        return arg1 + arg2

You've over done it a bit. First correct the two typos:

  • Error type is ValueError not "ErrorValue"
  • Error return value should be None not "none"

Then delete everything after the first return None. This should pass the challenge

Post back if you need more help. Good luck!!
