Use

Hi,
I`m a python newbie and could use some help.
I often do a loop over arbitrary number of sequences. I do it like this:

this isn`t nice I think. Is there some way I can say myiterator=geniousfunction(seq1,seq2,seq3)

Just ask for the values or the keys!
for value in pairs.values()
print value
for key in pairs.keys()
print key

print key
print value

Some others have already mentioned TurboGears, but since it sounds like
you want more control perhaps, I would recommend going with CherryPy
(http://www.cherrypy.org). You basically write python code and then
expose it to the web (or intranet or whatever).

Christian,You are certainly right. I couldn't get anything apart from "Hello world" coding in mod_python. The mod_python manual is also bit vague, not for beginners. I wonder why there aren't any good tutorials on mod_python.

A KeyError means you are trying to access an object that does not exist
in the dictionary. And this is true, you haven't added anything for Steven
Bates
yet, but you are trying to access his parents list.

No problem. As for the main use of cmp(), btw, afaik, it's
used to define custom sorting, as in the following:

It's an incorrect call to the base class __init__() function. This does
base class initialization on the current list. The correct call is
list.__init__(self)
By the way this list seems to be doin
Here is an exercise out of Learning Python:
Write a class called Mylist that shadows ("wraps") a
Python list: it should overload most list operators
and operations including +, indexing, iteration,

I'm new to python also. Have you come across any good exercises that a beginner try.
I've spend some time going throught the many available turorials, but find it hard to get good exercises to try out what you learn.

This should have worked, but there's one problem. Whenever we're doing

there can be some interference between the iteration and any readline()

Some starter 101:
First, recognize that a class is a compound type that is not only a type
but binds other variables and methods with it.
#-
# initialization of class
If you want to be able to give initial values to the class when it
is instantialized, you do it in the __init__ function that Terry
mentioned:
class People(object):
def __init__(self, firstname='Chris', lastname='Spears'):
