2,497 PointsHow to get numbers to float before adding them
I tried adding the float before the n1 .float((n1 + n2)) and did not work and tried this: def add(n1,n2): return .float((n1)) + .float((n2)) add(5,5) still not working where do I add the float?
def add(n1,n2):
return .float((n1)) + .float((n2))
add(5,5)

- there should be no period before the word "float"
- you only need to define the function, you don't need to call it yourself
- you only need one set of parentheses after each "float"

2,497 Pointsah ok. This is a bit different from JS I'm so used to putting "." before a function Thanks

231,210 PointsEven in JavaScript you wouldn't put a period before an ordinary function name, but you might put a period between an object name and a method name. Later you will discover that Python also has methods, and uses the same notation style (period in between).
And yes, Python is pretty different from most other languages you've probably used before. The key is to learn how to "think in Python"!

2,497 Pointsyeah thats what I meant. So what about the this? Its saying to use the try stmt if we dont get a number and the except stmt, but what would i put in the try? def add(n1,n2): try: except ValueError(return None) else: return float(n1) + float(n2) add(5,5)

231,210 PointsTo be sure your posted code is displayed correctly (with indentations, etc) you must use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. Or watch this video on code formatting.
But even looking at the scrambled code, I would remind you that you only will define the function, not call it. And for the exception handling to work, the float conversions must be done in the "try" section of the code.
