  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)
  
  # Example test cases
  # This function requires user input, so no assert statements are applicable.
