How Can I Make Asynchronous Requests with Python\'s `requests` Library?

Asynchronous Requests with Python requests

The Python requests library provides convenient asynchronous request handling through its async module. To execute asynchronous requests and retrieve the content of each response, follow these steps:

1. Define a function to process each response. In this function, you can access the response object and perform desired operations on its content.
2. Add the defined function as an event hook to your request using the hooks parameter. The hook will be triggered automatically when the request is completed.
3. Create a list to store all the requests or actions you want to execute asynchronously.
4. Use the async.map() function to execute the list of requests asynchronously.

For example, consider the following code snippet:

from requests import async

urls = [
    'http://python-requests.org',
    'http://httpbin.org',
    'http://python-guide.org',
    'http://kennethreitz.com'
]

def do_something(response):
    print(response.url)

async_list = []

for u in urls:
    action_item = async.get(u, hooks={'response': do_something})
    async_list.append(action_item)

async.map(async_list)

This code will asynchronously execute requests to the specified URLs and print the URL of each response to the console.
