I'd love this for python as I'm not a big fan of Ruby. Does such a thing exist?

Out of interest, why are you not a fan of Ruby?

  Not the parent but speaking myself, I feel the need to pick one or the other. I'm not saying I hate Ruby. I just haven't take the time (nor had a reason to, frankly) become a fan the way I have with Python. Being similar languages in terms of both being dynamic, malleable, mostly single threaded and REPL-able they both seem to occupy the same spot in my toolbox. Not to knock Ruby-the-language, but the one hitch is that Python's ecosystem is quite a bit vaster into fields I don't interact with (biology, physics, etc.) but also with many that I do (numpy/sympy, cli utilities and scripting, opencv, curl bindings). Where I'm at, it's most everyone's secondary or tertiary language. Nothing against Ruby, it's just circumstance. If anything I might pick it up soon if only to access JRuby/TruffleRuby worlds which are much ahead of Jython/GraalPython. Oh, except for function calls without (). And I'm not huge on DSLs. They seem icky but I grew to love significant whitespace in Python so maybe I'll grow to love those too.

  Right tool for the job; don't be a fan boy.

    As someone who prefers Python to Ruby, Ruby is better for this job because there are so many more methods on Array/Enumerable than on Python list (or Python's global functions.) And them all being methods makes life simpler too.

Several people have tried to tackle this in Python. My attempt was python-oneliner[1]. There's also a list of similar projects in the readme. [1] https://github.com/gvalkov/python-oneliner https://github.com/gvalkov/python-oneliner

Not well tested... just whipped this up. The example to sort df -h by the percent: df -h | p 'sorted({}[1:], key=lambda x: int(x.split()[-2][:-1]))' I saved this as ~/bin/p #!/usr/bin/env python3 import sys single_line = sys.argv[1] == '-l' code = ' '.join(sys.argv[2 if single_line else 1:]) if single_line: for line in sys.stdin: print(eval(code.format('line.strip()'))) else: print('\n'.join(eval(code.format('sys.stdin.read().splitlines()'))))

I made myself a little utility that's kinda like that: https://gist.github.com/dschep/4358be665537463b9271f782e77ff85f https://gist.github.com/dschep/4358be665537463b9271f782e77ff...
