      How can I filter a substring from payload?

      Payload, for example: b'HTTP/1.1 200 OK\r\nDate: Sat, 03 Dec 2016 15:52:20 GMT\r\nExpires: -1\r\nCache-Control: private, max-age=0\r\nContent-Type: text/html; charset=ISO-8859-1\r\nP3P: CP="This is not a P3P policy! Se....
      I want to get the substring between Date: and \r\n, for example. I allways get a type error
      Error: TypeError: can't convert 'str' object to str implicitly

        You have to convert the bytes type data to string first, e.g. with decode().

        str= b'HTTP/1.1 200 OK\r\nDate: Sat, 03 Dec 2016 15:52:20 GMT\r\nExpires: -1\r\nCache-Control: private, max-age=0\r\nContent-Type: text/html; charset=ISO-8859-1\r\nP3P: CP="This is not a P3P policy! Se...'.decode()

        Then you can apply the string operations.
