Hi,
I'm new to programming and I've tried to learn in the past but I gave up
easily. I tried learning Java but I feel that Python would be the best
route to take since it's easier to learn and then I'll move on to learning
Java. I want to learn Python 3.x not Python 2.
My goal(s) are:
Learn Python

He means use the Python interpreter, by going to your console and typing
"python", or in Windows
it's called 'IDLE'.

Learn Python within 1 month
That's achievable, at least to a working level.
Expert takes a tad longer.

Use modules instead of singleton classes
As a new beginner with Python, I am having problem understanding the
difference here.
I think I understand classes, but still have problems with inheritance,
but I do not understand what defines a module.

Whats a more pythony way to do this? I have a dict with a few dozen

Please post in plain text, not html.
A module is a source file (eg. .py) or a compiled source file (eg
.pyc) that's generally intended to be used via an import.

Can you describe the format a little more precisely? You're giving
examples, which is wonderful. But the examples are missing something.
What's the output you want to get here? Imagi

Hi Uma,
In your case, I'd look at the file as a sequence of "tokens" and look
at this as a tokenization problem
I think we'll see some kind of _identifier_, followed by _whitespace_,
followed by a _string_. All these three tokens will repeat, until we
hit the end of the the file.
More formally
Hi Ben,
There's a bit of duplication in the keys being looked up, making it a
bit fragile if you need to correct the spelling of a key or need to
add additional keys, since there are two places that need to be
changed.
One way to make this a little cleaner might be to have a helper
function that
