Here is how it could look like:
# make a new function 'add' # 'add' should take two arguments def add(num1, num2): # add a 'try' block try: # convert arguments to floats num1 = float(num1) num2 = float(num2) # then add an except to catch the possible 'ValueError' except ValueError: # inside the except block 'return None' return None # if following the structure from the videos add an 'else' for final return else: # add then together and return the total return num1 + num2
