Python asyncio blocks on coroutine but not websockets

Python's asyncio module provides a powerful framework for writing asynchronous code using coroutines. While it is commonly associated with web development and frameworks like aiohttp, asyncio is a versatile tool that can be applied to various asynchronous programming scenarios. In this tutorial, we'll explore how asyncio blocks can be used with coroutines to manage concurrent tasks without using websockets.
Make sure you have Python 3.5 or later installed on your system.
Before diving into asyncio blocks, let's briefly review what coroutines are and how asyncio utilizes them. In Python, coroutines are special functions that can be paused and resumed, allowing for asynchronous execution of tasks. The async def syntax is used to define coroutines:
In the above example, asyncio.sleep(2) is a non-blocking call, allowing other tasks to run during the sleep period.
Asyncio blocks provide a way to control the execution flow of coroutines. These blocks are essential for managing concurrency and ensuring that certain parts of code are executed sequentially or in a specific order.
The asyncio.gather() function allows you to execute multiple coroutines concurrently and await their results. This is particularly useful when you want to run several independent tasks simultaneously.
In this example, task_one() and task_two() are executed concurrently, and the await asyncio.gather() ensures that the main() coroutine waits for both tasks to complete.
The asyncio.Lock() class provides a way to synchronize access to shared resources. It prevents multiple coroutines from accessing the critical section simultaneously.
Here, the async with lock: statement ensures that only one coroutine can enter the critical section at a time.
The asyncio.Queue() class is useful for managing a queue of tasks that need to be processed asynchronously. Coroutines can enqueue and dequeue tasks from the queue.
Here, the producer() coroutine adds items to the queue, and the consumer() coroutine removes items from the queue.
Python's asyncio module offers a powerful and flexible framework for asynchronous programming using coroutines. By utilizing asyncio blocks such as asyncio.gather(), asyncio.Lock(), and asyncio.Queue(), you can manage concurrent tasks efficiently without the need for websockets. Asynchronous programming becomes especially beneficial when dealing with I/O-bound tasks, and asyncio provides a clean and concise syntax for handling such scenarios.
