zip函数-Python 3

zip函数接受任意多个(包括0个和1个)序列作为参数,返回一个tuple列表。

zip函数在获取数据后,生成字典(dict)时比较好用。

 

for examples:

 1 # Code based on Python 3.x
 2 # _*_ coding: utf-8 _*_
 3 # __Author: "LEMON"
 4 
 5 pList = [(li, LY, 80), (zeng, ZW, 90), (dudu, LR, 98)]
 6 names = []
 7 scores = []
 8 for i in range(len(pList)):
 9     aStr = pList[i][0]
10     bStr = pList[i][2]
11     names.append(aStr)
12     scores.append(bStr)
13 
14 
15 aDict = dict(zip(names, scores))
16 print(aDict)

运行结果:

1 {dudu: 98, zeng: 90, li: 80}

 

当然,上述案例有更简单的实现方法:

 1 # Code based on Python 3.x
 2 # _*_ coding: utf-8 _*_
 3 # __Author: "LEMON"
 4 
 5 pList = [(li, LY, 80), (zeng, ZW, 90), (dudu, LR, 98)]
 6 aDict = {}
 7 for data in pList:
 8     aDict[data[0]] = data[2]
 9     # dict[Key]=value
10 print(aDict)
