Hello,
The other day I was playing with a while loop with a for loop nested inside.
Within the for loop I had a condition to break the loop, but when loop ran it
never existed the loop. I went back and looked in Programming Python to read
about loops and I've got two questions (related to each

Your break is for the for loop not the while. The
Can you run for loops in while loops and if yes, why did my if condition not
break the loop?
I read that loops sort of have an order of precedence, does that have
anything to do with this problem?
todd,
welcome to Python! you're right in that your questions are related to
each other

I'm not sure if this is good practice, but I could assign a variable within the

Hi everyone,
Thanks for the comments Dave and Alan!
Based on these I have updated the code... I don't know if this is more
readable.
@Dave: I kept the original separate and combine function with bases as I
thought I would move them to a math library if I need to work in other
bases, however now

Nice!
Note that the list conversion is not needed; when you iterate over a string
you automatically get each character in turn:

It sounds like this is not the first assignment in the course. True?
If so did you complete them successfully?
If so is there anything in the prior assignments that you can build on?

Hi,
Does anyone know how to do a unittest assert for a type?
So If you have a program returning a Decimal, lets say Decimal(1), and you
want to make sure that what is returned is a Decimal object.
At first I thought of importing Decimal and making my own Decimal(1) and
doing an assertEquals,

Okay,
Thanks that worked.
I still needed to import the Decimal class and I'm not sure that is okay. The
reason why is I'm receiving the Decimal value from another program, if I
already know that the value will be a Decimal why test it?
Perhaps I'm getting to caught up in this test-driven

When possible, it's better to use assertEqual() rather than a

Hello,
I have some autogenerated code from Selenium which I cannot figure out
how to pass some command line variables to. For example I could export
the same in Perl and it would be for example:
code
use strict;
use warnings;
use Time::HiRes qw(sleep);
use Test::WWW::Selenium;
use Test::More
First off, selenium is a great tool and the python driver is very powerful
there are numerous ways to access cli variables,
the quickest
import sys
print sys.srgv
sys.argv will it output a array of all command line args

So I added the following:
