Dear all:
The mouse cannot be responded in the windows of python(command
line) and cut and paste cannot be done. ctrl c and ctrl v do not work.
But they do work in IDLE.
please teach me about the python(command line).

Dear Diez:
It is attaching a C-debugger to python. I can attach python-
debugger(for example:wingIDE) to c-debugger(for example:VS2008), but I
cannot attach VS2008 to wingIDE. I need both python statement and c
statement can be single-step debugged.
best regards

I find myself frequently in need of classes like this for two reasons.
First, it's efficient in memory. Second, when two instances are
compared for equality only their pointers are compared. (I think
that's how Python compares 'str's.

I mean, all the class instances that equal to each other should be
reduced into only one instance, which means for instances of this
class there's no difference between a is b and a==b.
Thank you.

Python is supposed to be readable, but after programming in Python for
a while I find my Python programs can be more obfuscated than their C/C
++ counterparts sometimes. Part of the reason is that with
heterogeneous lists/tuples at hand, I tend to stuff many things into
the list and *assume* a stru
Hi will,Thanks for your reply. The simplified code is as follows, and
you can run it if you like. It takes 7 seconds to process 1000 rows,
which is tolerable, but I wonder why it takes so long, because I also
did one for loop through all of the same rows without accessing array,
which only takes 1
Hi,
I am writing code to sort the columns according to the sum of each
column. The dataset is huge (50k rows x 300k cols), so i need to read
line by line and do the summation to avoid the out-of-memory problem.
But I don't know why it runs very slow, and part of the code is as
follows. I suspect i
Thank you guys. I've written a CYK parser and realized this is the
right direction. It gives every possible interpretation of the string
and I can retrieve whatever I want.

Thank you very much, Tim and Monkee.
In fact, what I'm doing is handle a lot of regular expressions. I
wanted to build VERY LONG regexps part by part and put them all into a
file for easy modification and maintenance. The idea is like this:
(*INT) = \d+
(*DECIMAL) = (*INT)\.(*INT)
(*FACTION) = (*
Oh, please do have a look at the second link I've posted. There's a
table comparing the regexp engines. The engines you've tested probably
all use an NFA implementation.

Basically, the problem is this:
>>> p = re.compile("do|dolittle")
>>> p.match("dolittle").group()
'do'
Python's NFA regexp engine trys only the first option, and happily
rests on that. There's another example:
>>> p = re.compile("one(self)?(selfsufficient)?")
>>> p.match("oneselfsufficient").gro

Hi, I'm learning STL and I wrote some simple code to compare the
efficiency of python and STL.
//C++

I wanna use nested lists as an array, but here's the problem:
>>> a = [[0]*3]*3
>>> a
[[0, 0, 0], [0, 0, 0], [0, 0, 0]]
>>> a[0][0] = 1
>>> a
[[1, 0, 0], [1, 0, 0], [1, 0, 0]]
Could anybody please explain to me why three values were change? I'm
bewildered. Thanks!

I wrote a function with a list as its parameter. And the function has
to perform different operations based on the datatypes of the elements.
How can I decide whether an object is, say, a list or a string?
Thanks.
