Python Network Programming

Python provides two levels of access to network programming. These are –

Low-Level Access: At the low level, you can access the basic socket support of the operating system. You can implement client and server for both connection-oriented and connectionless protocols.
High-Level Access: At the high level allows to implement protocols like HTTP, FTP, etc.

In this article, we will discuss Network Socket Programming. But before getting started let’s understand what are sockets.
