If the user enters anything other than a number, detect their mistake using try and except and print an error message and skip to the next number. Enter a number: 4 Enter a number: 5 Enter a number: bad data Invalid input Enter a number: 7 Enter a number: done 16 3 5.333333333333333

Answer 1

numbers = []

while True:
    try:
        number = input("Enter a number: ")
        if number == "done":
            break
        number = int(number)
        numbers.append(number)
    except ValueError:
        print("Invalid input")


print(sum(numbers), len(numbers), sum(numbers)/len(numbers))
