import requests_futures.sessions # Create a FuturesSession object session = requests_futures.sessions.FuturesSession() # Submit three POST requests future1 = session.post('http://example.com/post1', data={'foo': 'bar'}) future2 = session.post('http://example.com/post2', data={'foo': 'baz'}) future3 = session.post('http://example.com/post3', data={'foo': 'qux'}) # Wait for all requests to complete with a timeout of 5 seconds responses = requests_futures.sessions.as_completed([future1, future2, future3], timeout=5) # Print the response status codes for response in responses: print(response.status_code)In this example, we're creating a `FuturesSession` object and submitting three POST requests using `session.post()`. We then use the `as_completed()` method to wait for all requests to complete with a timeout of 5 seconds. Finally, we print the status codes of the responses. Overall, `requests_futures` is a useful package for making asynchronous HTTP requests in Python, with `FuturesSession.post()` providing a convenient way to submit POST requests asynchronously.
