If you think that parentheses are spelt with a "d", you're certainly
confused :-)
They're all brackets. Often the type of bracket doesn't matter,

Python doesn't check whether a type is already an iterator. It's
simpler to require that iterato

hi leon,
you made a good start and ran into something that i know doesn't seem right
to you. however, before we attack the issue, there are some basic problems
with the code you need to correct first. below are a few explanations and
perhaps workarounds:
1. you're passing in price *and* asking

Here is what I'm trying to do, accept a price of gas, but I want to add the
.009 to the price, so that people do not have to type the full amount.
Example, 3.49 /gallon would return 3.499 /gallon.
This is what I have tried and the results of it.

price == raw_input("What

Potentially distutils.spawn.find_executable might apply,

I guess there is a whole class of outliers; not really sure how to classify

Python can't see your file. You can check what python
is seeing by importing os and using listdir():

The file would appear to not be on your search path, that is, in any
directory in which Python is expecting to find it. Either move it to a
directory on your path, or change your path to include it's location.
The easiest way to find out what your path is, that I know, is
import sys
sys.path
