  def calculate_average():
      nums = []
      for i in range(5):
          nums.append(int(input("Please enter number: ")))
  
      #Calculate average
      average = sum(nums) / len(nums)
  
      #Print average
      print("The average is ", average)
      
  assert calculate_average() is not None
