Where to get a multithreaded python proxy checker?

Need a Proxy Checker in python Something I can't find a normal proxy checker in python: - check that the proxy is "live" - check for the proxy country - free of charge - work in a multi-thread ( you need to check 10000 proxies)

Perhaps there are ready-made options for me to write a normal vryatli myself?
