How does python handle multiple clients?

You can use use PySock, a python library that make writing multi-client servers extremally easy.

How do I create a multithreaded server in python?

Create Python Multi Threaded Server Socket Program ( and Python Client Socket Program ( in two separate files. Open a DOS prompt (console) and run the Server Program first. Then you will get the message “Server started” in Server side.

How do you accept multiple clients in socket programming?

A better way to handle multiple clients is by using select() linux command.

  1. Select command allows to monitor multiple file descriptors, waiting until one of the file descriptors become active.
  2. For example, if there is some data to be read on one of the sockets select will provide that information.

How many clients can a server socket connect to?

On the TCP level the tuple (source ip, source port, destination ip, destination port) must be unique for each simultaneous connection. That means a single client cannot open more than 65535 simultaneous connections to a single server. But a server can (theoretically) serve 65535 simultaneous connections per client.

How do I create a WebSocket server in Python?

WebSocket Client with Python Create a new File “” and import the packages as we did in our server code. Now let’s create a Python asynchronous function (also called coroutine). async def test(): We will use the connect function from the WebSockets module to build a WebSocket client connection.

What is multi threaded file server?

Multithreaded Server: A server having more than one thread is known as Multithreaded Server. When a client sends the request, a thread is generated through which a user can communicate with the server. We need to generate multiple threads to accept multiple requests from multiple clients at the same time.

Are Python sockets thread safe?

Unfortunately,The socket shared by multi-thread is not thread safe. Think about buffer two threads operate on with no lock.

How do servers handle multiple clients?

How many users can one server handle?

A Single CPU core will commonly handle an average of 220 to 250 concurrent connections simultaneously. If for instance, a website runs on a server that has a single CPU with 2 CPU cores, approximately 500 visitors may access and search the website at the same time.
