Is there a reason, why not to make python useful for practical one liners
to replace perl and awk?
There is page Powerful Python One-Liners,
https://wiki.python.org/moin/Powerful%20Python%20One-Liners.
But almost none of them handles files, behaves like unix filter
or is ugly – must import modules, etc.

It seems that the command line options like -a, -n, -p, -F are still free. :-)
https://docs.python.org/3/using/cmdline.html

Why not use them almost the same way as in Perl?
https://perldoc.perl.org/perlrun#-n
https://perldoc.perl.org/perlrun#-p
https://perldoc.perl.org/perlrun#-a
https://perldoc.perl.org/perlrun#-Fpattern

E.g. -n would be almost equivalent to

        import sys,os,re
        from fileinput import *
        for line in input():
                <-c code comes here>
        close()

-p will print(line) as last command of the for cycle.

Why to learn Perl/awk/datamash/mlr/…, for “one line like” tasks?

Thank you in advance
Hans
