Basics of Coroutines A coroutine is a special software construct that allows a program to pause and resume execution without losing the current execution context. Unlike threads and processes, coroutines run within a single thread and achieve concurrency through a scheduling mechanism, reducing the overhead of context switching and improving program execution efficiency. Coroutines are … Read more
Introduction What is a Thread 1) A thread is the smallest unit of scheduling in an operating system. 2) A thread is the actual executor of a process, consisting of a set of instructions (the owner of process resources). 3) Multiple threads within the same process share the same memory space, allowing for direct data … Read more
Introduction Asynchronous programming has become the standard solution for handling high concurrency scenarios in modern Python development. From web services to web scraping, from database operations to network communication, asynchronous programming can significantly enhance the concurrent processing capabilities of programs without increasing thread overhead. With the introduction of the <span>async/await</span> syntax in Python 3.5, asynchronous … Read more
Word count: 2380, reading time approximately 12 minutes Python AsyncIO: A Guide to Learning and Usage The recommended way to declare coroutines for writing asyncio applications is through the async/await syntax. Mastering asyncio programming is essential for improving Python execution efficiency! Asynchronous I/O is a concurrent programming model, not parallel programming. asyncio asyncio is a … Read more
It’s time to supplement some knowledge about <span>asyncio</span>… The following content is extracted from the video by <span>gemini-2.5-pro</span> corresponding to <span>Corey Schafer</span>‘s video on YTB, provided as a backup for reference, and the original video is recommended for learning. This is the second part; the first part can be found in the Python asyncio Tutorial: … Read more
In modern software development, we often need to handle a large number of IO operations, such as network requests, file reading and writing, and database queries. Traditional synchronous programming methods can block the program during these operations, leading to poor performance. This is where asynchronous programming becomes particularly important. Python’s asyncio library is a powerful … Read more

Mastering Python can change your life; using Python effectively can greatly enhance your efficiency!—— Follow me to open a world of efficiency with Python.In AI development related to large models and agent development, we need to handle a large number of tasks simultaneously. Many people think of using multithreading (threading) for this, which is certainly … Read more
aiohttp: Asynchronous HTTP Framework to Enhance Network Request Performance! Friends, today let’s talk about aiohttp! When it comes to network requests, many people might think of requests, which is a very popular synchronous HTTP library. However, if you need to efficiently handle a large number of network requests, such as web scraping, API calls, or … Read more
High-Performance Python Programming: A Comprehensive Guide to Performance Optimization Python has become one of the preferred languages for developers due to its simple syntax and rich ecosystem, but its interpreted nature is often criticized for insufficient execution efficiency. This article will start from the core theories of performance optimization, combined with practical cases, to systematically … Read more
