Here you will find simple python 2.7 files which demonstrate a pattern for workig with multi-core processors.
These files and instructions are based on work with a Raspberry Pi 3 Model B running Debian Jessie but the general pattern should work on other systems with a multi-core processor.
For a detailed discussion of the ues of these files see the blog post "Easy muiti-core programming with Python" at: https://xperimentia.com/2016/05/25/easy-muiti-core-programming-with-python/
