python如何爬取疫情數據

這篇文章給大家分享的是有關python如何爬取疫情數據的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。

疫情數據

程序源碼

// An highlighted block
import requests
import json
class epidemic_data():
  def __init__(self, province):
    self.url = url
    self.header = header

    self.text = r.text
    # self.r = r
  def parse_page(self):
    # print(type(self.r.json()['data']))
    # 因為解析數據為 data 前有一個""，所以數據類型為string
    data_str = json.loads(self.text)['data'] #sring
    # print(type(data_dict))
    # print(type(data_dict['data']))
    # 將str 轉化為對象
