Socket Programming with Multi-threading in Python
Prerequisite : Socket Programming in Python, Multi-threading in Python
Socket Programming-> It helps us to connect a client to a server. Client is message sender and receiver and server is just a listener that works on data sent by client.
What is a Thread?
A thread is a light-weight process that does not require much memory overhead, they are cheaper than processes.
What is Multi-threading Socket Programming?
Multithreading is a process of executing multiple threads simultaneously in a single process.
Multi-threading Modules :
A _thread module & threading module is used for multi-threading in python, these modules help in synchronization and provide a lock to a thread in use.
from _thread import * import threading
A lock object is created by->
print_lock = threading.Lock()
A lock has two states, “locked” or “unlocked”. It has two basic methods acquire() and release(). When the state is unlocked print_lock.acquire() is used to change state to locked and print_lock.release() is used to change state to unlock.
The function thread.start_new_thread() is used to start a new thread and return its identifier. The first argument is the function to call and its second argument is a tuple containing the positional list of arguments.
Let’s study client-server multithreading socket programming by code-
Note:-The code works with python3.
Multi-threaded Server Code
Python3
Console Window: socket binded to port 12345 socket is listening Connected to : 127.0.0.1 : 11600 Bye
Client Code
Python
Console Window: Received from the server : skeegrofskeeg syas ayruahs Do you want to continue(y/n) :y Received from the server : skeegrofskeeg syas ayruahs Do you want to continue(y/n) :n Process finished with exit code 0
