Python爬虫 | 美国特斯拉充电桩位置信息(含经纬度)爬取

warning: 这篇文章距离上次修改已过218天,其中的内容可能已经有所变动。

概要

最近在搞美赛模拟,2018D题需要用到特斯拉在美国的两种充电桩(一种是Supercharger,另一种是Destination Charging)的位置数据。下面介绍如何用Python在Tesla官网爬取已经建立的充电桩所在州、县、详细地址、经纬度坐标以及FIPS等信息,以及即将建立的充电桩的大致位置和计划建造时间。

requests2.26.0\
regex2021.8.3Python自带正则表达式模块
progressbar24.0.0用于在控制台显示进度条

代码

由于两种充电桩的数据页面基本一样,所以以下代码可以抓取两类充电桩的数据。记得在 # 索引页面root下面的requests.get()里面修改source为数据来源里写的网页,并且在代码末尾修改保存csv的名称避免覆盖。

#!/usr/bin/env python
