python - 如何在打印结果时显示某些输出？

Question

下面是我使用的代码。

# display a welcome message
print("===============================================================")
print("Shipping Calculator")
print("===============================================================")

while True:

    # get input from the user
    cost_of_items = float(input("Cost of items ordered:  "))

    # make sure input is a positive number
    if cost_of_items < 0:
        print("You must enter a positive number. Please try again.")
        continue
    
    # to do: get shipping cost(one given for example)
    
    if cost_of_items < 30:
        shipping_cost = 5.95
        
    if 30.00 < cost_of_items < 49.99:
        shipping_cost = 7.95
        
    if 50.00 < cost_of_items < 74.99:
        shipping_cost = 9.95
    
    if cost_of_items > 75:
        shipping_cost = 0
        
    # To do: calculate total cost: total_cost
    total_cost = cost_of_items + shipping_cost

    # to do: display in output, print shipping cost, print total cost
    print(shipping_cost,total_cost)
    
    # to do: make your program more interesting, ask user how many item like to ship, 
    num_of_items = float(input("Number of items to ship:  "))
    
    # and caclutate the cost of shipping based on total cost
    total_shipping_cost = shipping_cost*num_of_items
    final_total_cost = cost_of_items + total_shipping_cost
    print(total_shipping_cost, final_total_cost)


    # see if the user wants to continue
    choice = input("Continue? (y/n): ")
    print("===============================================================")
    if choice.lower() != "y":
        break
        
print("Bye!")

这是我得到的输出: enter image description here

但我希望输出显示如下:

enter image description here

我该怎么做？在输出前放一些描述？比如要运送的商品数量:X，总运费:XX

您正在尝试创建多行字符串。这可以简单地用 "\n"

来完成

例子:

# String containing newline characters
line_str = "I'm learning Python.\nI refer to TechBeamers.com tutorials.\nIt is the most 
popular site for Python programmers."

这应该使它看起来像:

“我正在学习 Python。”

我引用了 TechBeamers.com 教程。

这是最Python 程序员的热门网站。”
