pthon中的嵌套

1、列表中嵌套字典

a1 = {'color':'green', 'points':5}
a2 = {'color':'yello', 'points':25}
a3 = {'color':'red', 'points':15}

ass = [a1, a2, a3]

for a in ass:
    print(a)

输出结果：

 

2、字典中添加列表

pizza={
'curst':'thick',
'toppings': ['mushroom','extra cheese']
}

print("Your order: " + pizza['curst'] + "-pizza" +
"with the following toppings:")

for topping in pizza['toppings']:
　　print(' '+topping)

示例结果：

3、在字典中存储字典

users = {
　　'ast1':{
　　'first':'albert',
　　'last':'en',
　　'location':'henan'
　　},

　　'ast2':{
　　'first':'marry',
　　'last':'cur',
　　'location':'paris'
　　}
}

for username, use_info in users.items():
　　print(' username: '+ username)
　　fullname = use_info['first'] + " " + use_info['last']
　　location = use_info['location']

　　print(" Full name: " + fullname.title())
　　print(" location: " + location.title())

示例结果：
