Installation and usage
python3 -m pip install asynchrony
A simple example of starting concurrent tasks for all URLs (maximum 100 tasks at the same time) and waiting for all of them to finish:
from asynchrony import Tasks
async def download_page(url: str) -> bytes:
...
urls = [...]
tasks = Tasks[bytes](timeout=10, max_concurrency=100)
tasks.map(urls, download_page)
try:
pages = await tasks
except Exception:
failed = sum(t.failed for t in tasks)
print(f'{failed} tasks failed')
cancelled = sum(t.cancelled for t in tasks)
print(f'{cancelled} tasks cancelled')
else:
print(f'finished {len(tasks)} tasks')
See tutorial for runnable usage examples.
