input: Write a function to calculate the average of five numbers entered by a user. The function should prompt the user to input five numbers, calculate their average, and then print the average. If the user enters less than five numbers, the function should handle the error appropriately.

      average = sum(nums) / len(nums)
  
      # Print average
      print("The average is ", average)
