car = input("What kind of car do you want?")
print("Let me see if I can find you a %s"%car)
7-2 餐馆订位:编写一个程序,询问用户有多少人用餐。如果超过8人,就打印一条消息,指出没有空桌;否则指出有空桌。
num = input("How many persons?")
num = int(num)
if num > 8:
print("There is no table for you.")
else:
print("There is a table for you.")
7.3 10的整数倍:让用户输入一个数字,并指出这个数字是否是10的整数倍。
num = input("Please input a number:")
num = int(num)
if num % 10:
print("It's not the mutiple of 10.")
else:
print("It's the mutiple of 10.")
7-4 比萨配料 :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。
item = input("Please input the ingredient of pizza(input 'quit' to end):")
while item != 'quit':
print("We will add %s in the pizza."%item)
item = input()
7-7 无限循环:编写一个没完没了的循环,并运行它(要结束该循环,可按Ctrl+C,也可关闭显示输出的窗口)。
while True:
print("Hello!")
7-8 熟食店:创建一个名为sandwich_orders的列表,在其中包含各种三明治的名字;再创建一个名为finished_sandwiches的空列表。遍历列表sandwich_orders,对于其中的每种三明治,都打印一条消息,如I made your tuna sandwich,并将其移到列表finished_sandwiches。所有三明治都制作好后,打印一条消息,将这些三明治列出来。
sandwich_orders = ['beef','ham','egg','pork']
finished_sandwiches = []
while sandwich_orders:
sandwich = sandwich_orders.pop()
print("I made your %s sandwich"%sandwich)
finished_sandwiches.append(sandwich)
print("All sandwiches finished")
for sandwich in finished_sandwiches:
print(sandwich + " sandwich")
7-10 梦想的度假胜地:编写一个程序,调查用户梦想的度假胜地。使用类似于“If you could visit one place in the world, where would you go?”的提示,并编写一个打印调查结果的代码块。
place = input('If you could visit one place in the world, where would you go?')
print("You want to go to %s"%place)
