How to create a thread using class in Python

In this article, you will learn how to create a thread in Python using classes. But first, let us learn what a thread is. When a process is scheduled for execution, the smallest unit of processing for execution is known as a thread. 

In Python, multitasking is achieved by multithreading.

Starting a new thread in Python

thread.start_new_thread ( func, args[, kwargs] )

It works both in windows as well as Linux.

Thread using class

But first, let us understand, what exactly is a class.

  • Now, In the code below, we can see how a thread is created using class.
  • The class name here is abc.
  • Two objects namely obj and obj1 are created inside the class abc.
  • Obj.start() initialises the thread.
import threading

class abc(threading.Thread) :
    def run(self) :
        for _ in range (2) :
obj= abc(name='Hello')
obj1= abc(name='Bye')



Advantages of Threading in Python

  1. If a computer system contains multiple CPUs, multiple threads can execute simultaneously. Therefore more programs can execute at the same time, increasing the speed of the process.
  2. Responsive to input in both the case of single and multiple CPUs.
  3. Local variables exist in threads.
  4. A global variable, if changed in one thread causes a change in all other threads as well i.e memory of global variable is shared in threads.
