python怎样获取json数据类型？

page = 1

param = {

    'currentPage': page

}

# 伪装火狐

kv = {'User-Agent': 'Mozilla/5.0'}

response = requests.get(url, params=param, headers=kv)

data = response.text

#通过正则获取"id":value列表

datalist = re.findall(r'\"id\":.*?(?=,)', data)

#打印datalist

print(datalist)

datalist2 = re.findall(r'\"rateDate\":\".*?\"', data)

print(datalist2)
