That's a trite response.  Complexity, power, and culture differ between languages.  In Perl, people make a game out of doing as much in a single line as possible.  Experts do things that are mystifying to a beginner.  In Python, an expert would be expected to produce a solution that is comprehensible to a less-expert programmer, spanning however many lines as are necessary.  It would be un-Pythonic to write code that a less expert programmer couldn't understand.
