I love interview questions that make Python look awesome.

  python -c "print '\n'.join(open('file.txt').readlines()[::-1])" Hmmm, slightly longer then the Perl version ;-) python -c "print '\n'.join(reversed(list(open('test.py'))))" Somewhat more elegant, but still lots of parentheses.

    It's also wrong - "readlines" keeps the "\n", and you've added another one between lines.
    • Luyt 17y ago
      Indeed. A cosmetic refinement, but it should really be: python -c "print ''.join(reversed(list(open('test.py'))))" That's even two characters less!

        Good, but too easy. Assume you can't keep the file in memory.
