Hi,
I've experience working at companies where, because of the network set
up, having a long PYTHONPATH and searching it is quite a heavy task
and can slow down the start up of the interpreter when there are lots
of imports.
As a proof of concept I wanted to look at a map-based approach. The

Actually, I used .readline() to parse file line by line, because I need
to find out the start position to extract data into list, and the end

What are the types of your sort keys?
If you're on 3.x and the key you need reversed is numeric, you can negate
the key.
If you're on 2.x, you can use an object with a __cmp__ method to compare
objects however you require.
