12.27 python 学习笔记

1.元组

numbers = (1,2,3)

元组里面的项目不可以修改(用圆括号)

2.解压缩

coordinates = (1,2,3)
x,y,z = coordinates
print(x,y,z)

>>1 2 3

3.字典

customer = {
    "name" : "John smith",
    "age" : 30,
    "is_verified":True
}
print(customer["name"])

>> John smith

4. 按空格分割

message = input (">")
words = message.split(' ')
print(words)

>Good morning

["Good" , "morning"]

5.函数

def greet_user():
    print('Hi there!')
    print('Welcome aboard')


print('Start')
greet_user()
print("Finish")

函数后面需要空两行
