Python - What do these two lines do? -

-
being new python, i'm having heck of time figuring out these 2 lines do: for in [j j in xrange(0, n) if [k k in xrange(j) if now[k] == now[j]] == []]: j in [k k in xrange(1, k + 1) if [l l in xrange(i) if now[l] == k] == []]: is there way rewrite noobs myself understand it? thanks. i'm positive code equivalent to: for in range(0, n): prefix = set(now[:i]) if now[i] in prefix: continue j in range(1, k + 1): if j in prefix: continue # or (which bit less efficient, nicely reflects idea behind code): for i, j in itertools.product(range(0, n), range(1, k + 1)): prefix = now[:i] if now[i] not in prefix , j not in prefix: # , j but it's written in convulted, inefficient way (especially [...] == [] nasty , pointless). maybe feels pretty clever using complex structures simple ones better suited.

Can JQuery or JavaScript be used to manipulate XML/DOM without a browser? -

-
i starting study web technologies integrate content, markup, layout, styling , behaviors of stuff personal use (not web developing now) , amazed power of jquery selectors , functions. i have heard there ways use javascript "outside" browser, dom selection, manipulation, etc. wonder if jquery used way too. so, is: using programming/scripting language (i use python), access xml file , parse dom; programmatically manipulate , modify dom javascript/jquery selectors , functions; save results (possibly another) xml file. if jquery syntax, check out pyquery : from pyquery import pyquery _ = pyquery('<body><p></p></body>') _("p").text("hello").css({'color': 'red'}) print _.html() >>> <p style="color: red">hello</p>
