python-aiohttpMaking request in background with Python Aiohttp?

Making requests in background with Python Aiohttp is a great way to make asynchronous requests. It allows you to make multiple requests at once, without having to wait for each one to finish before making the next.

Example code

import aiohttp

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    async with aiohttp.ClientSession() as session:
        html = await fetch(session, 'http://example.com')
        print(html)

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Output example

<html>
    <head>
        <title>Example Domain</title>
    </head>
    <body>
        <h1>Example Domain</h1>
        <p>This domain is established to be used for illustrative examples in documents. You may use this
        domain in examples without prior coordination or asking for permission.</p>
    </body>
</html>

Code explanation

import aiohttp: This imports the aiohttp library, which is used to make asynchronous requests.
async def fetch(session, url):: This defines a function that takes a session and a URL as parameters. It then makes an asynchronous request to the URL and returns the response text.
async def main():: This defines a function that is used to make the actual requests. It creates a ClientSession object, which is used to make the requests, and then calls the fetch function to make the requests.
if __name__ == '__main__':: This is used to check if the code is being run directly, and if so, it creates an event loop and runs the main function.
