I'm still working through Chun's Core Python Applications. I got the
web crawler (Example 9-2) working after I found a ':' typing error. Now
I'm trying to convert that to a program that checks for broken links.
This is not in the book. The problem I'm having now is knowing whether

Programming and can't get one of the examples to actually work. In
trying to analyze the problem (good learning approach) I had troubles
understanding the interactions between the two classes of objects. As

I have been working my way through Chun's book /Core Python Applications.
/In chapter 9 he has a web crawler program that essentially copies all
the files from a web site by finding and downloading the links on that
domain.
One of the classes has a procedure definition, and I'm having

Hi, im trying to write a script which randomly generates 10,000 points(x,y)
in the unit square(so range between 0 and 1 for both x and y).
so far I have written the code below in red, however it only produces one
random point. How do I get it to repeat this so it produces 10,000 different
random
I've been trying to learn Python, writing a Blackjack program. Seems
that's a common problem for learning. I'm not in a class or school,
just working on my own. I've been working in Python 2.7, and
considering moving up to 3.x. My programming background is ancient,

I'm trying to iterate over a list of elements, and make changes to the list
in front of the element I'm currently working with. I can update the list,
but the 'for' doesn't see the new element. Here's the code:

items = items[:point+1][:] +
I'm just learning Python, so I apologize for a newby question. I'm trying
to work with lists of lists, the lowest level of which hold one or more
tuples. I've tried to condense what I've tried. The code is:
#! Python 2.7
import copy
list = []
for i in range(8):
list.append((i, i+1))
H =
You are fundamentally correct about my confusion, though I'm trying to work
with tuples as the lowest level, which may not be relevant here.
