Number of available processors in Python

Question

In Java, this will return the number of available processors:

Runtime.getRuntime().availableProcessors()

This is handy when deciding how many long running threads to create.

Is there an equivalent function to call in Python?

Ack! I was looking through stackoverflow for days trying to find that. I was finding it hard to believe that no one had asked this already. Thank you Ruturaj! — dstrube, Apr 10 '19 at 12:29
