In this tutorial, you'll learn how to send data from client-to-server and client-to-client connections using socket programming in Python.
Socket programming is the implementation of two sockets to send and receive data bi-directionally at any given moment. It connects two sockets (or nodes) together and allows them to communicate in real time. Internet-connected applications that need to operate in real time greatly benefit from the implementation of sockets in their networking code, allowing data to be sent and received at any time.
In this Python tutorial, you'll learn how to send data from client-to-server and client-to-client connections using socket network programming in Python. You'll also learn how you can leverage the power of PubNub to send data between two or more client devices for peer-to-peer communication using the PubNub Python SDK. Although this tutorial guides you step-by-step through this process, you can view a video walkthrough of this tutorial on YouTube and find the source code for this application in the GitHub repository.
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
