Hey, it would be awesome to have something like this for Python!

Not really possible in Python for anything overly useful/complex because of the significant white space, and regular expressions are not a first class object in the language. ipython is the equivalent solution I suppose. However, Ruby completely inherited this aspect of Perl and is another good candidate. It's just even old systems have a perl installed that will perform the awk like functionality.

  There is "Pyed Piper" aka `pyp` https://code.google.com/archive/p/pyp/ https://code.google.com/archive/p/pyp/ "Pyp is a linux command line text manipulation tool similar to awk or sed, but which uses standard python string and list methods as well as custom functions evolved to generate fast results in an intense production environment."

    That's cool, but I feel like you're unlikely to run into it very often in the wild? The vast majority of Linux systems come with ruby/perl out of the box. Plus if Python did support this sort of hackery it would quickly garner most of the bad press Perl has over the years :'(

      Who cares? It's on pypi (https://pypi.python.org/pypi/pyp/2.11 https://pypi.python.org/pypi/pyp/2.11) so just `pip install pyp` and then you have it. You're probably not going to want to distribute shell scripts that rely on pyp, but if you're distributing scripts you can just distribute scripts written entirely in Python and use pyp for your own one-liners.

  The lack of something like Perl/Ruby's -n and -p switches is a barrier as well. Those are handy because they automatically work for either piped input, or files named on the command line. Of course, you can do all of this in Python, just not as a one liner.

I wrote a little tool called "pyline" about a hundred years ago... I still reach for it often when I'm in a hurry, and don't have time to futz around with awk/sed. https://code.activestate.com/recipes/437932-pyline-a-grep-like-sed-like-command-line-tool/ https://code.activestate.com/recipes/437932-pyline-a-grep-li...
