I was having a look at the UNIX philosophy and I readed that:
"Make every program a filter
This makes it easy to build a set of filter components into ``one big 
filter.'' Programs can communicate by explicitly reading and writing 
files; that is / much / more complex to manage, and requires a lot of 
disk I/O for interim output. A set of filters may pass data straight 
from memory buffer to memory buffer, avoiding disk altogether."

I was wondering how I could be able to make my python programs work in a 
filter mode?
