一般情况下
x,y,z = 1,2,3 print("x:",x) print("y:",y) print("z:",z)
#运行结果 x: 1 y: 2 z: 3
对元祖序列解包
name = ("qiaobushi","wanglihong","leibushi") x,y,z = name print(name) print("x:",x) print("y:",y) print("z:",z)
#运行结果 ('qiaobushi', 'wanglihong', 'leibushi') x: qiaobushi y: wanglihong z: leibushi
对列表序列解包
str = "123,456,789" str = str.split(",") print(str) x,y,z = str print("x:",x) print("y:",y) print("z:",z)
#运行结果 ['123', '456', '789'] x: 123 y: 456 z: 789
对dict序列解包获得key和value
#例1 dict1 = {"one":1,"two":2,"three":3} x,y,z = dict1 print("key-x:",x) print("key-y:",y) print("key-z:",z) print("value-x:",dict1[x]) print("value-y:",dict1[y]) print("value-z:",dict1[z]) #例2 dict1 = {"one":1} x,y = dict1.popitem() print("key:",x,"value:",y)
#运行结果 key-x: one key-y: two key-z: three value-x: 1 value-y: 2 value-z: 3 key: one value: 1
以上这篇python-序列解包(对可迭代元素的快速取值方法)就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持。
