Hey Vikshith,

You're using hard coded values as your arguments, which will cause the second step of this challenge to fail.

Try switching your arguments to variables, and rather than grouping them together when you call the float function, call the function once on each variable.

def add(a, b):

    return float(a) + float(b)

Good luck with the course!

Also, I'm going to leave the code that will pass for the third stage here, since you're likely to struggle with that one considering you got stuck in the second stage.

Keep in mind that this is a cleaner way to complete the challenge than other methods that will pass, so I encourage you to mess around and try a few things before looking at the answer provided.

Note that this passing code does not use the else clause that could be used if you're following the structure shown in the videos.

def add(a, b):

    try:

        return float(a) + float(b)

    except ValueError:

        return None
