Python timeit Tutorial: How to Measure Code Execution Time

When developing Python applications, performance tuning is an indispensable step. However, if you measure code execution time using manual methods like time.time() or time.perf_counter(), the results are often noisy due to interference from system background tasks, the Garbage Collection (GC) mechanism, or system clock resolution. To thoroughly solve this problem, Python provides the built-in timeit […]

asyncio.gather() in Python: Efficient Async Programming Guide

In modern Python programming, asyncio has become the core library for handling asynchronous programming. When you need to execute multiple I/O-bound tasks concurrently (such as calling APIs, querying databases, reading/writing files, or web scraping), the asyncio.gather() function is a powerful tool to save waiting time and optimize performance to the maximum. This article from DCSOFT […]
