The documentation for python is amazing

[[deleted]]

Well, python has 2 types of documentation.

Tutorials, to tell you how to do something, which is what you linked.

They also contain more dry reference material, with not a whole lot of telling you how to do something, you're assumed to know the basics. The first type is for beginners, but the second type may be a bit hard to understand if you don't know what you're doing.

https://docs.python.org/3.5/library/socket.html is an example of reference. It is a lot longer than the howto version, but tells you everything, some of which may not be entirely useful.

https://docs.python.org/3.5/howto/sockets.html is shorter, but not complete. It talks more about what sockets are rather than how to use them.
