对于上篇中，预处理后的结构化数据，本篇希望对其进行数据的格式化输出。
主要目标是：根据地点id，起止时间段的设定，在条件筛选下得到对应的数据，并格式化输出到本地文件中。
上篇中最后得到的结构化数据：

比如我想得到id为12的place，其时间区间为 2017-08-28 00:00:00 到 2017-08-29 12:00:00
优化后的python程序如下：
# -*- coding: UTF-8 -*-
#import numpy as np
import pandas as pd
from pandas import Series, DataFrame
#from dateutil.parser import parse
records = pd.read_csv('./macdata/normal_origin_info_test.txt',names=['time','idplace','mac'])
#读取文件，records的数据结构为dataframe，设定列名为[time,idplace,mac。
pid = 12
#设定place id 为12
start_time = '2017-08-28 00:00:00'
#设定起始时间
end_time = '2017-08-29 12:00:00'
#设定截止时间
def getInfoByIdpidtime(idplace,stime,etime):
#定义查询函数
s = stime[5:7]+stime[8:10]
#格式化起始时间
e = etime[5:7]+etime[8:10]
#格式化截止时间
idplaceinfo_test = records[ (records['idplace'] == idplace) & (records['time'] > stime) & (records['time'] < etime) ]
#条件筛选 依照dataframe语法规范
outputpath = './macdata/selectinfo/' + 'place_' + str(idplace) + '_' + s + '-' + e + '.csv'
#设定输出路径和输出文件名
idplaceinfo_test.to_csv(outputpath, header=False, index=False)
getInfoByIdpidtime(pid,start_time,end_time)
#执行查询
最终得到的数据如下：
