It's just a preference thing, I loathe the small program chaining style and cannot work with it at all. Give me a python script and I'm good though. I can't for the life of me imagine why people would want to do pseudo programming through piping magic when chaining is so limited compared to actual programming

[samatman]

This is of course a false dichotomy, there's nothing pseudo about using bash (perhaps you mean sudo?) and bash scripts orchestrate what you call 'actual' programs.

I commonly write little python scripts to filter logs, which I have read from stdin. That means I can filter a log to stdout:

   cat logfile.log | python parse_logs.py

Or filter them as they're generated:

   tail -f logfile.log | python parse_logs.py

Or write the filtered output to a file:

   cat logfile.log | python parse_logs.py > filtered.log 

Or both:

   tail -f logfile.log | python parse_logs.py | tee filtered.log

It would be possible, I suppose, to configure a single python script to do all those things, with flags or whatever.

But who on Earth has the time for that?

Chaining pipes in python is quite obnoxious.
