Asyncio Coroutines - Learn Data Science with Travis

Asyncio-Coroutines

Asyncio coroutines are a fundamental aspect of asynchronous programming in Python, enabling efficient execution of concurrent tasks. Defined using the async def syntax, coroutines can pause their execution with the await keyword, allowing other tasks to run in the meantime. This non-blocking behavior is particularly beneficial for I/O-bound operations, where waiting for data or network responses can slow down a program. By leveraging asyncio, developers can create responsive applications that handle multiple tasks simultaneously, improving performance and user experience. Understanding coroutines is essential for mastering asynchronous programming in Python.

Asyncio Benchmark Helper Coroutine

Super Fast Python

You can develop a helper coroutine to record and report the overall execution time of coroutines and tasks in asyncio programs. The helper coroutine can be implemented using a try-finally block so tha...

Asyncio Coroutine Function and Coroutine Types

Super Fast Python

You can programmatically identify coroutine functions and coroutines using the inspect module API. Coroutines have a specific “coroutine” type that shares methods with generators as well as the awaita...

Asyncio Concurrent Tasks

Super Fast Python

We can execute asyncio tasks and coroutines concurrently, a main benefit of using asyncio. There are four main ways that we can achieve this, including issuing coroutines as independent tasks and awai...

Asyncio Coroutine Object Methods in Python

Super Fast Python

We can define coroutine methods on custom Python objects. This allows methods on custom Python objects to use async/await syntax, such as awaiting other coroutines and tasks and allows the custom coro...

Asyncio Coroutines Faster Than Threads!?

Super Fast Python

You can benchmark the performance of coroutines, threads, and processes on a suite of (simulated) common tasks. This is helpful to explore a refrain that “coroutines are faster than threads“, and the ...

How to Execute Multiple Coroutines with asyncio.Runner

Super Fast Python

You can execute multiple coroutines in the same event loop using the asyncio.Runner class in the high-level asyncio API. This is a new feature provided in Python 3.11. Before the addition of the async...

Coroutines
