A little bit stuck...

Hi All!

Im having a little bit of trouble on this question.

it keeps saying name error - test.

I want to make num = test so that I can turn test into an interger??

However it keeps saying name test undefined...have I not defined it???

Thanks!

squared.py 
# EXAMPLES
# squared(5) would return 25
# squared("2") would return 4
# squared("tim") would return "timtimtim"
def squared(num):
    num = test
    try:
        num = int(test)
        return (test ** 2)
    except TypeError:
        return (len(test) * num)

I got it working by REMOVING TYPE ERROR.

Why did TypeError make it not work???

Hi Greg,

I moved this to the answer section and selected best answer since you solved your own question.

To answer your follow up question, see the following python:

>>> int("xyz")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: 'xyz'
>>>

As you can see from that, when you try to convert a non numeric value, a ValueError is raised and not a TypeError.

You could have passed the challenge if you had caught a ValueError. But in this case, the challenge only requires that you catch the exceptions.

Hello

Because it should be ValueError and not TypeError

Ok thanks...I thought ValueError was when you cant mix an integer and a string...

I guess thats a TypeError...wont make that mistake again:D
