Yes, using Python is mainly because of object-oriented programming paradigm.
It's handy to have encapsulation of functionality in methods, one can do
unit-testing of parts of the script. Currently AWK scripts are mix of input/output
transformation and various emission of printf('#error..') sanity checks.
In general the script is not easily readable and contains multiple global arrays
that simulate encapsulation in classes.
