trial.py Python basics test help. The last questions asks to use try: and I am having difficulty with syntax I think
MY CODE: def add(num, nums): try: return(float(num) + float(nums)) except ValueError: return None else: return(add)
Q1. Not sure what to return in else: Q2. what is wront with syntax that the test fails every time...
def add(num, nums): try: return(float(num) + float(nums)) except ValueError: return None else: return(add)
This is what the problem asks for:
You're doing great! Just one more task but it's a bigger one. Right now, we turn everything into a float. That's great so long as we're getting numbers or numbers as a string. We should handle cases where we get a non-number, though. Add a try block before where you turn your arguments into floats. Then add an except to catch the possible ValueError. Inside the except block, return None. If you're following the structure from the videos, add an else: for your final return of the added floats.
So its looking for an else.
I tried the following as well.. still no luck. I tried a lot of different indentions....
`def add(num1, num2): try: plus = (float(num1) + float(num2)) except: ValueError: return (None) else: return (plus)

You have a bit of an indentation issue. The "try", "except" and "else" should all line up vertically. And the "def" line should start at the first column.
Also, you don't really need the "else". Since both the "try" and "except" sections have a "return", the "else" will never get used.
