一般情况
x,y,z = 1,2,3 print("x:",x) # x:1 print("y:",y) # y:2 print("z:",z) # z:3
针对元祖
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 ‘‘‘
针对字符串
a,b,c=‘hel‘ print(a) print(b) print(c) # h # e # l
针对列表
# 定义绩效列表 list = [10,3,5,6,22,8,12,44] # 需求:只要开头和结尾的数值 # *代表中间所有的 _代表一个变量,因为我们不想要了,所以使用_,*后面必须跟一个变量 a,*_,c=list print(a) print(c) # 10 # 44 a,*d,c=list print(a) # 10 print(d) # [3, 5, 6, 22, 8, 12] print(c) # 44
针对dict序列解包获得key和value
#法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]) #法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 ‘‘‘
对变量的值进行交换
f1=1 f2=2 # 需求把f1和f2的值进行交换 # f1,f2=f2,f1 print(f1,f2) # 2 1
