The last article gives you the absolute basics of using Python. This
time, we'll do the OO side of Python. Yes, Python: a true object-
oriented language with classes, inheritance and all.
Ok, my OO background comes from the

I just noticed that in your code you used pop(0). It's not efficient
to pop an element off the front of a list because after doing so,
every other element in the list has to be moved over to the left one
position. If you pop() an element off the end of the list, then the
first element in the list

When you define a function like this:
def func(**keywordargs):
print keywordargs
the function expects to receive arguments
kwargs is not a built in name--it's a made up name used in the
docs.Would you expect this function to work:

Per the pysqlite installation instructions, this is the test I ran to
confirm that pysqlite installed correctly
>from pysqlite2 import test
>test.test()
and I got output similar to what the docs say should happen:

They are never the same unless you only add one item to the list.
append() will only increase the length of a list by 1.
la = [1,2]
lb = [3, 4, 5]
la += lb
print la
lc = [1,2]
lc.append(lb)
print lc

This is the syntax the docs describe:
---
Python Reference Library
10.10.1:
When called as a program from the command line, the following form is
used:
python timeit.py [-n N] [-r N] [-s S] [-t] [-c] [-h] [statement ...]

Not "Learning Python: From Novice to Professional". I've looked at
"Learning Python 2nd Ed." to use as a reference for all the blunders
in the first book I mentioned, and it's a lot better--plus it has
exercises at the end of each chapter.
