Found a good-looking realisation for making asynchronous HTTP requests in this article: https://www.twilio.com/blog/asynchronous-http-requests-in-python-with-aiohttp Here is the code I tried to use:
import aiohttp
import asyncio
import time
start_time = time.time()
async def get_pokemon(session, url):
async with session.get(url) as resp:
pokemon = await resp.json()
return pokemon['name']
async def main():
async with aiohttp.ClientSession() as session:
tasks = []
for number in range(1, 151):
url = f'https://pokeapi.co/api/v2/pokemon/{number}'
tasks.append(asyncio.ensure_future(get_pokemon(session, url)))
original_pokemon = await asyncio.gather(*tasks)
for pokemon in original_pokemon:
print(pokemon)
asyncio.run(main())
print("--- %s seconds ---" % (time.time() - start_time))
But it gives me this:
...
\--- 0.7400617599487305 seconds ---

I also tried closing session manually and using asyncio.create_task for tasks list, both didn't change anything.
