while循环 动手试一试

1.创建一个三明治列表，其中包含各种三明治名，至少保证‘pastrami’出现三次，在创建一个空列表，对每种三明治打印一条信息，比如i made your tuna sandwich,并将其移动空列表中，所有三明治制作好后，打印一条消息，将这些三明治都列出了。

orders=['Arepa','Pastrami','Croque Madame','Smoked Meat','Pastrami','Doner Kebab','Arepa','Pastrami','Tuna']
finished=[]
while orders:
    a=orders.pop()
    print('I made your %s sandwich.'%(a))
    finished.append(a)
print(sorted(finished))

2.在开头打印一条消息，指出pastrami已经卖完了，在使用一个循环将order中的pastrami删除，确认最终的列表中不含有pastrami

orders=['Arepa','Pastrami','Croque Madame','Smoked Meat','Pastrami','Doner Kebab','Arepa','Pastrami','Tuna']
finished=[]
print('Pastrami is sold out.')
while 'Pastrami' in orders:
    orders.remove('Pastrami')
while orders:
    a=orders.pop()
    print('I made your %s sandwich.'%(a))
    finished.append(a)
print(sorted(finished))

3.调查用户梦想度假胜地，并编写一个打印调查结果代码块

dic={}
flag=True
while flag:
    name=input('What is your name?')
    place=input('If you could visit one place in the world,where would you go?')
    dic[name]=place
    a=input('Anyone else? or quit')
    if a.lower() =='quit':
        flag=False
for i,v in dic.items():
    print(i,'want to visit',v)
