Stuck on this problem please help
We should handle cases where we get a non-number, though. Add a try block before where you turn your arguments into floats. Then add an except to catch the possible ValueError. Inside the except block, return None. If you're following the structure from the videos, add an else: for your final return of the added floats.
def add(gain,mike): try: except ValueError: return(None) else: return(float(gain) + float(mike))

Two people have already provided answers the last time you asked this question. One of them even gave you the exact answer.
If you're still confused, it would be better if you responded with what you are still confused about on that question rather than just asking the question again.
