As a Python developer, you might have come across the concept of asynchronous programming. Asynchronous programming, or async I/O, is a concurrent programming design that has received dedicated support in Python, evolving rapidly from Python 3.4 through 3.7 and beyond. With async I/O, you can manage multiple tasks concurrently without the complexities of parallel programming, … Read more
As a Python developer, you might be familiar with lambda functions, which provide a simple and concise way to create anonymous functions. However, when it comes to asynchronous programming, you may wonder if it is possible to use async and await within lambda functions to create “async lambdas.” Currently, Python does not natively support async … Read more
Asyncio Overview Asyncio is a Python library that allows you to write asynchronous code, providing an event loop, coroutines, and tasks to help manage concurrency without the need for parallelism.With asyncio, you can develop high-performance applications that harness the power of asynchronous programming, without running into callback hell or dealing with the complexity of threads. … Read more
As a Python developer, you may often deal with making HTTP requests to interact with APIs or to retrieve information from web pages. By default, these requests can be slow and block your program’s execution, making your code less efficient. This is where Python’s async requests come to the rescue. Asynchronous HTTP requests allow your … Read more
In Python, the async for construct allows you to iterate over asynchronous iterators, which yield values from asynchronous operations. You’ll use it when working with asynchronous libraries or frameworks where data fetching or processing happens asynchronously, such as reading from databases or making HTTP requests. The async for loop ensures that while waiting for data, … Read more
Python’s async and await are powerful features that enable you to write asynchronous code to improve the performance of your applications, particularly when dealing with I/O-bound and high-level structured network code. Async and await are used with coroutines, which are special functions that can pause and resume their execution at specific points. This allows multiple … Read more
