Return Added Floats

Hello,

I'm confused about what the floats do to my arguments. For the last challenge, I believe my code is correct up to the line else: Here's how it looks. def add(two, three) try: return float(two) + float(three) except ValueError: return(None) Else: return(two + three)

I'm unsure of how to correct this.

Thanks!

trial.py 
def add(two, three):
try:    
    return float(two) + float(three)
except ValueError:
    return(None)
else:
    two + three

def add(two, three): try:

Bharath,

I tried that, but it didn't seem to work. I'm still confused about the floats. Can someone explain that to me?

Thanks,

Hi Andrew,

The float() function takes in an integer or a string argument and turns it into a floating point value, which is basically a number that contains a decimal point. For example: if you pass an integer value of 5 to the float(5) function, you will get back 5.0. Similarly, if you pass a string value float("5"), you will still get back 5.0. BTW I tried the code and it works for me. What happens when you are trying to run the code? Hope this is clear.

Thanks, Bharath
