我们要获取每个地区的kfc信息就要先获取中国一共有哪些地区

中国所有城市名称获取

import requests
from lxml import etreewith open(f'./省份.txt', 'w') as fp:fp.write('')
with open(f'./城市.txt', 'w') as fp:fp.write('')url1='http://www.kfc.com.cn/kfccda/storelist/index.aspx'#页面网址
city=[]
res1=requests.get(url1).text
tre=etree.HTML(res1)
sheng=tre.xpath('//*[@id="container"]/div[1]/div[2]/div/div[1]/div[1]/div/div[3]/ul/li/strong/text()')
#得到页面源码
n=len(sheng)
for i in range(1,n+1):shi=tre.xpath(f'//*[@id="container"]/div[1]/div[2]/div/div[1]/div[1]/div/div[3]/ul/li[{i}]/div/a/text()')#使用xpath对信息获取for s in shi:city.append(sheng[i-1]+'-'+s)
print(city)
for i in city:with open(f'./城市.txt', 'a') as fp:fp.write(i+'\n')
for i in sheng:with open(f'./省份.txt', 'a') as fp:fp.write(i+'\n')

现在我们已经有了每个城市的名字我们只需要将他们替换到请求接口的data中即可获取每个地区的kfc门店基本信息

每个地区门店基本信息获取
