Advantages and sample code of Python multithreading

Multithreading is a concurrency technique used in programming that allows a program to perform multiple tasks simultaneously. As a high-level programming language that supports multi-threaded programming, Python provides a multi-threading module ( threading) to implement multi-threaded operations. The advantages of Python multi-threading will be introduced below and corresponding sample codes will be given.

  1. Improve program performance: Multi-threading allows a program to handle multiple tasks at the same time while executing tasks, thereby improving the overall performance of the program. When there are time-consuming operations in the program, such as network requests, file reading and writing, or computationally intensive tasks, using multi-threading can take full advantage of multi-core processors and speed up the processing of tasks.

  2. Increase program responsiveness: Multi-threading can make programs more responsive. In a single-threaded program, if a task takes a long time, the entire program will be blocked and unable to respond to other events. By using multi-threading, long-term tasks can be processed in one thread while keeping other threads running, so that the program can respond to user input and other events in a timely manner.

  3. Improved user experience: Multithreading can improve the user experience of interactive applications. For example, in graphical user interface (GUI) applications, using multi-threading can execute time-consuming operations in background threads, keeping the interface smooth and responsive so that users will not feel stuck or unresponsive.

Here is a simple example code showing how to use multithreading in Python:

import threading
import time

def task(
