def add(arg1,arg2): try: float(arg1) float(arg2) except ValueError: return none else: return float(arg1) + float(arg2)
not sure why this code is wrong

16,266 PointsYour indentation is wrong, except
and else
seem to be inside the try
block, whereas they should be on the same level -
try:
# code
except:
# code
else:
# code

9,664 PointsYour try block should suffice without the need for an else statement. Try returns the addition between both arguments, shall we pass something other than an "integer" or number as arguments a ValueError is "raised", in this case we are already using the exception as an else statement, "if ValueError is presented do this instead", which is to return None
def add(x, y):
try:
return float(x) + float(y)
except ValueError:
return None
