Python——使用高德API获取指定城指定类别POI并实现XLSX文件合并

  1 import xlrd # 读xlsx
 import xlsxwriter # 写xlsx
 import urllib.request # url请求，Python3自带，Python2与3中urllib的区别见：http://blog.csdn.net/Jurbo/article/details/52313636
 import os # 创建output文件夹
 import glob # 获取文件夹下文件名称
 import time # 记录时间
 import json # 读取json格式文件

 # 本函数完成文件合并。单独保存是为了1.方便不同的用途；2.减少内存；3.在应用到其他网站时，可以断点续爬，降低中断风险
