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)
