Learn asynchronous programming with asyncio.
Build high-performance Python applications.
Basic async
import asyncio
async def fetch_data():
await asyncio.sleep(1)
return “data”
async def main():
result = await fetch_data()
print(result)
asyncio.run(main())
Concurrent Tasks
async def fetch_all(urls):
tasks = [fetch_url(u) for u in urls]
return await asyncio.gather(*tasks)
aiohttp
import aiohttp
async with aiohttp.ClientSession() as session:
async with session.get(url) as response:
return await response.json()
Conclusion
Async Python improves performance significantly!
