Alberto,
To convert any algorithm to python (or anything else) you have to understand
it. Do you know what AWK is doing? And does the darn thing work already in
awk? Why do you need to convert it? My suspicion is that it has errors and
if so, it is NOT about converting at all.
I will not solve
things and clearly the original programmer used some.
Which brings us back to languages like python. When I started using AWK and
a slew of other UNIX programs years ago, what I found interesting is how
much AWK was patterned a bit on the C language, not a surprise as the K in

A generator that opens one file at a time (or STDIN) in a consistent manner,
