How to implement multithreading?

Question

Python

It is necessary to implement some real multithreading in the script.
The essence of the script:
The script expects a command with a number. As soon as the number is received, the script starts parsing the page on the site using the number (it doesn't matter though). BUT! While parsing a page, the script MUST continue to wait and accept values ​​from users and start parsing other pages in parallel.
Attention to the question - how to do it?
Can you recommend any libraries or example. The threading library does not seem to suit me, because in fact it does not seem to make a multithread, but stops the rest of the threads while one of them is running.
If I'm wrong, tell me.

Answer 1

asyncio is all you need.

asyncio is a library to write concurrent code using the async/await syntax.
asyncio is used as a foundation for multiple Python asynchronous frameworks that provide high-performance network and web-servers, database connection libraries, distributed task queues , etc.
asyncio is often a perfect fit for IO-bound and high-level structured network code.
