Python Python Basics (2015) Logic in Python Try and Except

Add a try block before where you turn your arguments into floats. Then add an except to catch the possible ValueError.

Stuck again and hope to get some help.

def add(one, two):

numbers= float(one) + float(two)

except  ValueError:
        return None
         return numbers

Looks like its a problem of mostly just your spacing, I have reformatted it for you. Try this.

def add(one,two):
        one = float(one)
        two = float(two)
    except ValueError:
        return None
        return one+two

Thank you Christopher for the reply. I actually slowed the problem already.
