Python入门习题大全——索引

编写一个循环，提示用户输入一系列的比萨配料，并在用户输入’quit’时结束循环。每当用户输入一种配料后，都打印一条消息， 说我们会在比萨 中添加这种配料。

# 比萨配料
prompt = "Please add something: "
prompt += "\n(Enter 'quit' when you finished.)\n"
active = True
while active:
    sth = input(prompt)
    if sth == 'quit':
        active = False
    else:
        print("\nWe'll add it!\n")

输出为：

(Enter 'quit' when you finished.)
