Whan I run the following function, I see a mem leak, a 20 mb of memory
is allocated and is not freed. Here is the code I run:
>>> import esauth
>>> for i in range(100):
... ss = esauth.penc('sumer')

Don't forget to free(buf). ;)

Sorry, Here is the correct output:

Hi all,
This might be a newbie question. I am trying to implement a simple
string decoder/encoder algorithm. Just suppose I am substrcating some
values from the string passed as a parameter to the function and I
want the function to return encoded/decoded version of the string.

I'm writing my first 'real' program, i.e. that has a purpose aside from
serving as a learning exercise. I'm posting to solicit comments about my
efforts at translating strings from an external source into useful data,
regarding efficiency and 'pythonicity' both. My only significant

This criterion is pretty much a deal
I need to parse the following string:
$$\pmatrix{{\it x_2}\cr 0\cr 1\cr }=\pmatrix{\left({{{\it m_2}\,s^2
}\over{k}}+1\right)\,{\it x_1}-{{F}\over{k}}\cr -{{{\it m_2}\,s^2\,F

BeautifulSoup (http://www.crummy.com/software/BeautifulSoup/) makes HTML
parsing easy as pie, and sufficiently old versions seem to work with Jython.

Try BeautifoulSoup, which handles malformed pages pretty well.
