How to make full use of CPU cores with threading in python 2

Question

The following code seems to be executed sequentially rather than concurrently. And it only made use of one CPU core. Is there a way to make it use multiple cores or switch cont

Answer 1

A friend of mine asked me this once. In your case, just use multiprocessing.process and that will use all your cores.

Answer 2

Threads cannot utilize multiple cores in Python. Processes however can.

multiprocessing is a package that supports spawning processes using an API similar to the threading module. The multiprocessing package offers both local and remote concurrency, effectively side-stepping the Global Interpreter Lock by using subprocesses instead of threads. Due to this, the multiprocessing module allows the programmer to fully leverage multiple processors on a given machine. It runs on both Unix and Windows.
