正则findall 错误，refindall 怎么是一个元祖？不是列表吗

Question

value = re.findall(r'.*?<Cookie\s*k=(.*?)\s*for.*?<Cookie tk=(.*?)\s+',
    str(self.s.get("http://e.oppomobile.com/cpdStat/trend", headers=self.headers).cookies))
print value
tk_value = value[1]
k_value = value[0]

Answer 1

cookies取值不需要通过正则，你直接使用索引就行了
比如你的cookies取tk值

self.s.cookies['tk']

Answer 2

获取cookie的方法楼上已经说了，关于正则，你这里使用了两个分组，就是（.*?）所以列表里的每个元素是两个分组匹配结果构成的元组

Answer 3

re.findall 怎么是一个列表？不是元组吗？
