how do you debug inside the challenges? I don't know why this code isn't working. Is it looking for a different format?
def add(arg1,arg2): try: num = float(arg1) + float(arg2) except ValueError: return(None) else: return(num)
add("one",4)
def add(arg1,arg2):
try:
num = float(arg1) + float(arg2)
except ValueError:
return(None)
else:
return(num)
add("one",4)

add("one",4)
It will raise a ValueError and would prevent your code from passing if you have it in the challenge. This code passes fine for me. The only other note that I make is that return doesn't require (and it's not Python convention) for parentheses to be around the value(s) that it's returning.
def add(arg1, arg2):
try:
added = float(arg1) + float(arg2)
except ValueError:
return None
else:
return added

I usually try to write the code in a IDE. AN IDE like PyCharm will naturally correct most of your syntax errors. I bought Pycharm just to do this course, it works great at getting you to write PEP8 standard. https://www.python.org/dev/peps/pep-0008/
This is one of my favorite things about Python, it's a beautifully clean and easy language read and write. Ever try javascript? ;-)

I've written a bit of javascript, java, and Swift. The syntax drives me crazy. I started on Python and I don't want to switch.
