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：

 # Code based on Python 3.x
 # _*_ coding: utf-8 _*_
 # __Author: "LEMON"

 pList = [('li', 'LY', 80), ('zeng', 'ZW', 90), ('dudu', 'LR', 98)]
 names = []
 scores = []
 for i in range(len(pList)):
     aStr = pList[i][0]
     bStr = pList[i][2]
     names.append(aStr)
     scores.append(bStr)

 aDict = dict(zip(names, scores))
 print(aDict)

运行结果：

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

当然，上述案例有更简单的实现方法：

 # Code based on Python 3.x
 # _*_ coding: utf-8 _*_
 # __Author: "LEMON"

 pList = [('li', 'LY', 80), ('zeng', 'ZW', 90), ('dudu', 'LR', 98)]
 aDict = {}
 for data in pList:
     aDict[data[0]] = data[2]
     # dict[Key]=value
 print(aDict)
