  assert calculate_average()==("<The user entered numbers and the average was calculated>")
output: def calculate_average():
      numbers = []
      for i in range(5):
          numbers.append(float(input()))
      average = sum(numbers) / len(numbers)
      print(f"<The user entered numbers and the average was calculated: {average}>")
