Beginner: Code not work when longer list

[deanhystad]

Instead of checking for "done", check if len(inp) == 0 or if inp == "". Now you just print <Enter> without entering a number to exit.

Or you could exit on any non-number input.

numbers = list()
try:
    while True:
        numbers.append(float(input("Enter a number:")))
except ValueError:  # Raised by float(str) when str is not a numeric string.
    print(f"Average{numbers} = {sum(numbers) / len(numbers)}")
