Hi all,

thanks for posting that, Jacob. Many things about the 'net are 
wonderful, but the relative anonymity isn't (always) among them!

I'm closing out 31, and as married as a consistent philosophical 
anarchist without present need of EU working papers can be ;-)

I'm Canadian, living in Montreal, and finishing up a PhD in the 
philosophy of logic. (So, I can clear a dinner-party in pretty good 
time.) The PhD thing leaves me with only Python and photography as 
hobbies. Came to Python via an ESR essay; its my sole programming 
language past some BASIC back in high-school.

While I've yet to explore python's logic related tools, it has been 
quite illuminating for my research interests to see recursion theory 'in 
action' rather than in the more purely abstract context that prevails in

Well I was guessing so I am happy that one of the guesses was correct. What happened when you tried 
'\xc2'?

[xml text cut]

Hi Kumar,

Just as a side note: have you looked at Biopython yet?

    http://biopython.org/

I mention this because Biopython comes with parsers for BLAST; it's
possible that you may not even need to touch XML parsing if the BLAST
parsers in Biopython are sufficiently good.  Other people have already
solved the parsing problem for BLAST: you may be able to take advantage of
that work.

Ok, I see that you are trying to get the content of the High Scoring Pair
(HSP) query and hit coordinates.

Re: Parsing a block of XML text

Hi Danny, 
  Thanks for your reply. I have been using BioPython
for long time. I found their BLAST parser buggy
(IMPO), otherwise BioPython has more cool modules. 

In my case Parser did not iterate over hits and it
turned out difficult for me to look into it in detail.
Also, I wanted to work more on my own so that I get
more understanding over parsing XML documents. 

I was about to post to the list seeking some
systematic explanation to the example on PLR. 
http://www.python.org/doc/lib/dom-example.html

Frankly it looked more complex. could I request you to
explain your pseudocode. It is confusing when you say
call a function within another function.

Using £ in python

Kent,

When I tried '\xc2' nothing happened.
I should have said that is a game using pygame.

It seems like forever to someone who hasn't seen before 1990. : )

I seem to hear that a lot on the list...

I might need that...

Help with testing.

Hi,

    A little while back somebody suggested doctesting, I think it was. Well,
anyway, it was the testing that took testing material from the doc strings
of functions in the format of an interpreter and the desired result (example
below). Could anyone help by pointing me to structured documentation on how
to use this, or even the name of the testing module(s)?
Even nicer, a way to put the testing code in a seperate module so all I have
to do is something like...

pseudocode

def test(obj):
    ## Testing particulars -- parameter is a module.function that has a
docstring with testing material

m = raw_input('What is the module? ')
n = raw_input('What is the function? ')
obj = eval(m+'.'+n)  ## Given that I'm the only one who will be using it and
I will not try to crack my computer...
test(obj)

Ohhhhh..
and the doc string example...

def function(a,b):
    """A function to do what you want it to.

    >>> function('3','a')
    '3a'

Re: How to put my functions in an array

Hello.

    I believe it was Danny Yoo who told me about mapping functions a while
back on the list...
It goes along these lines...

Stuff':more,"Extras":extra}
def addvirt():
    pass
def remvirt():
    pass
def more():
    pass
def extra():
    pass
def dispatch(name):
    if name:

    else:

Re: How to substitute an element of a list as a pattern forre.compile()

Nobody explicitly mentioned that you're trying to make a pattern from an
integer and not a string, which, I believe is required. Also, Rich needs to
make the % formatting "%d"%x   instead of  "%s"%x  because he showed that x
is an integer not a string.

There's my two bits.

*args, **kwargs

Hi,

I gave this a quick read: http://aspn.activestate.com/ASPN/Mail/Message/573292

I'm wondering how I can turn a variable number of keyword arguments
passed to a class into variables for use in said class:

#This so doesn't work

class SomethingLikeThis:
    def __init__(self, **kwargs):
        self.kwargs = kwargs

    def show(self):
        for k in self.kwargs.keys():
            v = selfkwargs.get(k)
            print v

I'm probably misunderstanding the purpose of *args and **kwargs totally.
