Why the third print stement output "'comments': [(1, 2, 3)]", I think
it should be [].
I am using
Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)]
on win32.
# program
class PicInfo:

I want to add some simple search function for my homepage. It need to
search through all the html files of my homepage (about 300 pages), and
highlight the search words.
I made some test with HTMLParser, it works but slow. So, my question is
how can I improve its speed?
from HTMLParser import HTM
I want to join two mono wave file to a stereo wave file by only using
the default python module.
Here is my program, but it is much slower than the C version, so how
can I increase the speed?
I think the problem is at line #1, #2, #3.
import wave
import array
lfile = wave.open(lfilename)
rfile = w
I think
oarray = array.array("h", [0]*(len(larray)+len(rarray))) #1
oarray[0::2] = larray#2
oarray[1::2] = rarray#3
will be executed at C level, but if I use itertools, the program is
executed at Python level. So the itertools

Yes. I want this for years. I am Chinese, and teaching some 12 years
old children learning programming. The biggest problem is we cannot
use Chinese words for the identifiers. As the program source becomes

Because the students can remember some English
I have the following questions, I am using Python 2.4.2
>>> a = [1,2,3]
>>> id(a.append)
19167152 #1
>>> id(list.append)
11306608 #1
1. the address of a.append and list.append is different, can I get the
address of list.append from a.append?
>>> id(a.append.__doc__)
19162720

Does this means there is no method to get the original methods from

Thanks, now I know I cannot use id() for my problem.
Here is my problem:
I want to add a docstring translator into the Python interpreter. If

I know about im_func, but I tried the im_func attribute of append and
I get error: 'built
Why the exec time of test(readdata()) and test(randomdata()) of
following program is different?
my test file 150Hz10dB.wav has 2586024 samples, so I set randomdata
function
to return a list with 2586024 samples.
the exec result is:
2586024
10.8603842736
2586024
2.16525233979
test(randomdata()) is
Thanks, by your hint, I change type(data) to type(data[0]), and I get
So, calculate with float is about 5x faster numpy.float64.

I need to write functions that return locals() as follows,
def func1():
a = 1
return locals()
def func2():
b = 2
return locals()
Can I write a decorator that it can automately do this conversion
def func1()
a = 1
--->
def func1():
a = 1
return locals()
