when using recursion should one use a return statement or not?
there is a difference obv since with a return statement it will
ultimately return a value if not recursing forever.
but is there a guideline for this or it just taste or is it
considering good style or pythonic to always have a return
im writing a webcrawler.
after visiting a new site i want to store it in alphabetical order.
so obv i want fast insert. i want to delete duplicates too.
which datastructure is best for this?

http://mail.python.org/mailman/listinfo/python-list
i have some confusion over this.
sure a class is basically a classification, like for example an animal
or flower. and an object/instance of that class is then for example a
cat.
an object is an instance of a class. that i know, i also know how to
program with classes etc.
i am just confused abo
i am writing a simple webspider .
how do i avoid getting stuck at something like this:
Enter username for W3CACL at www.w3.org:
?
i can obv add an if-clause for the specific site but since i guess
there will be more of the same thats ov not a viable approach in the
long run.

when running a very computationalheavy program in the shell it
sometimes freezes but the commandprompt runs it without problems and
muh faster, why?
also, the command prompt starts at C:\Users\user>
i want to start at C:\python25\progs
how do i change that?

i want to search a document for a particular regexp and then store
that regexp to a file.
but search and match only returns matchobjects(what are those anyway?
i dont get what to do with them, do they contain true/false,
stringposition etc?)
how do i do:
for rows in file:
print regexp.find #
import Tkinter
from Tkinter import *
i have a program where if i comment out either of those import-
statements i get an error.
i thought they meant the same thing and from was supposed to be just
to imort just a specific function and the * imports everything in the
module.
but aparently the abov

i am confused.
x=5
y=5
x==y -> True
x is y -> True
shouldnt x is y return False since they shouldnt(dont?) point to the
same place in memory, they just store an equal value?
