Trial.py float num1 + num2

To start, I don't want someone just to give me the answer.

I guess I'm kinda confused about how to use float correctly here. I've tried putting float in add, for both and each num I've attempted to put it in return, which gives an error I've tried to add float for both individual number in add(15, 2) and each individual.

Did we learn how to use float()? Did I sleep thorough this class? lol

trial.py 
def add(num1, um2):
    return(num1 + num2)
add(15, 2)

def add(num1, num2):
    return float(num1) + float(num2)

While I did say that I didn't want to just be given the answer, i'll take it, but with another question.

I tried this method and it didn't work for me before because I had return and float, for each, parenthesis still up. so like...

return (float(num1) + float(num2))

When should I or should I not continue to use parenthesis when it's needed at first? when I'm giving a different value, such as float to the 'X'?

Hey parenthesis are really not need in python 3 just use -

return float(num1) + float(num2)

you can also do -

def add(float(num1), float(num2)):
    return num1 + num2

sorry for the direct answer but its to straight forward, so I think it seemed fine.

BUT NOTE - if you think that parenthesis makes your code easy to read you can use them, its your choice.
