You'd probably better explain in English which things truly need to be
compared with what. Right now, your first version is, I believe, an O(n^4)
algorithm, which is extremely expensive, while your second (set-based)
version appears to be O(n^3), which is quite a bit better, but still not
stellar.
You could try Jython.
Other than that, you probably want a threadpool, or perhaps to try
multiprocessing - but that much forking could be a problem as well.

To just split lines into words, you could probably just use a regex.

Cython's very nice if you don't plan to do more than C/C++ with Python.
SWIG might be better if you intend to do more VHLL's than Pyth
Hm, maybe curses? *ix programmers often know what it is, but it was present
on VMS as well. And the python sources come with a curses module.
http://h71000.www7.hp.com/doc/732final/5763/5763pro_015.html
The main question then becomes, was VMS's curses a termcap curses or a
terminfo curses, or so
You're probably best off with Pyjamas. Then you get something that runs on
the web and on the desktop, from the same code - similar to GWT, but for
Python. The desktop version runs overtop of CPython, the web version is
AJAX and is automatically translated from a very 2.x-ish dialect of Python
to

Catenate the lists into a new list. Then randomize the order of the new
list by iterating over each element in turn, swapping it with a random
element elsewhere in the same list (optionally including swapping it with
itself - that's easier and still gives good randomization). This gives
linear ti

If you just want to be unhappy about the current situation, I hereby
formally bestow upon you permission to be so. :)
The problem seems to be that you want to hook into the python process,
without hooking into the python process. Were this possible, it seems we
might have a serious security issu

For open() or os.open(), it should look in your Current Working Directory
(CWD). Your python's CWD defaults to what the CWD was when python was
started, and it is changed with os.chdir().
Absolute paths will of course be relative to / on most OS's (or C:/ if
you're on C:, D:/ if you're on D:, etc
Are you on windows?
You probably should use / as your directory separator in Python, not \. In
Python, and most other programming languages, \ starts an escape sequence,
so to introduce a literal \, you either need to prefix your string with r
(r"\foo\bar") or double your backslashes ("\\foo\\bar
Actually, I'd probably create a class with 3 arguments - an initial value, a
lower bound, and an upper bound, give it a _check method, and call _check
from the various operator methods. The class would otherwise impersonate an
int.
In code that isn't performance-critical, it's better to check for
