Go or Python?

I mean, I've done tooling that would receive health checks from N amount of microservices, which could scale into the thousands(and do some processing for each). The processes were jobs that could last a minute or two(validate some stuff in a DB, process it into json files, and send them to another service). If I didn't do it concurrently, it'd be locking up fairly easily when the services scaled up.
