Три способа выполнить множество задач с asyncio Функция для примера: async def do_it(n): await asyncio.sleep(random.uniform(0.5, 1)) return n 1. Последовательный вызов async def main(): for i in range(100): result = await do_it(i) Такой вызов имеет смысл только тогда, когда результат одной задачи требуется для вызова следующей. Если они независимы, то это антипаттерн, так как аналогичен простому синхронному вызову по очереди. 2. Упорядоченный результат async def main(): tasks = [do_it(i) for i in range(100)] results = await asyncio.gather(*tasks) Выполняет корутины конкурентно и возвращает результат в виде списка. Полезен когда требуется получить результаты в том же порядке в котором задачи отправлены. 3. Результат по мере готовности tasks = [asyncio.create_task(do_it(i)) for i in range(100)] for cor in asyncio.as_completed(tasks): result = await cor Так же выполняет корутины конкурентно, но не гарантирует порядок. Результат возвращается по мере готовности, каждый отдельно. Полезен когда нужно обработать любой ответ как можно скорее. #async

https://medium.com/towards-data-science/using-scrapy-to-build-your-own-dataset-64ea2d7d4673 In short, #Scrapy is a framework built to build web scrapers more easily and relieve the pain of maintaining them. Basically, it allows you to focus on the data extraction using #CSS selectors and choosing XPath expressions and less on the intricate internals of how spiders are supposed to work.

#python#crawler#feapder#feaplat#python#scrapy#spider Feapder is a simple, powerful Python web scraping framework (Python 3.6+) with four spider types for different needs, plus breakpoint resuming, monitoring alerts, browser rendering, and massive data deduplication. Install easily via pip (basic, render, or full versions), create a spider with one command, and run it to fetch/parse sites like Baidu. A management system handles deployment/scheduling. This saves you time by making scraping fast, reliable, and scalable without building everything from scratch. https://github.com/Boris-code/feapder
