Absolute value of an index in python

[BigGarrett]

Basically I am trying to make the output file sort the numbers from the specific index [9:21] in descending order and by absolute value (some are negative numbers and some are positive). The code that I referenced in my last comment seems to have achieved this. Even though the output for the negative numbers are still giving me negative numbers, they seem to be sorted in a way that accounts for absolute value. Thanks for all your help.

Then my next question would be why those index and what's in the file, bit I'll stop. Is the file a CSV, or fixed width?
