This article mainly introduces "how to use python to make subway operation dynamic diagram of first-tier cities". In daily operation, I believe many people have doubts about how to use python to make subway operation dynamic diagram of first-tier cities. Xiaobian consulted all kinds of materials and sorted out simple and easy operation methods. I hope to help you answer the doubts of "how to use python to make subway operation dynamic diagram of first-tier cities"! Next, please follow the small series to learn together!

First, prepare the data. Take Beijing City as an example, grab the package on the subway page of Gaode Map

Beijing City subway information interface:

http://map.amap.com/service/subway?_ 1599997789354=&srhdata=1100_drw_beijing.json

Parse json data into Bmap data format

import requests import jsonurl='http://map.amap.com/service/subway?_ 1599997789354=&srhdata=1100_drw_beijing.json' response=requests.get(url)result=json.loads(response.text)stations=[]for i in result['l']: station=[] for j in i['st']: station.append([float(k) for k in j['sl'].split(',')]) stations.append(station) print(stations)
