hello community,i am a newbie to python and program in general.
the script below works in python 2.7.3 on windows but not in the python 2.7.3
ubuntu terminal.
>>>fp=open("prez.dat","r")>>>x=fp.read>>>(print(x)***i used fp for file
>>>pointer.I am using windows 7 and it works but on ubuntu 12.04
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
Good
+--+++
| | __iter__ | __next__ |
+--+++
| iterable | return an iterator | not available |

| i
I should have mentioned, the other possibility is that the file does
not, in fact, exist, but I assume you put it out there somewhere?

Python does not use a search path for the open() function, only for
imports. With open(), it uses a simple rul

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

os.listdir(',') # . is

Potentially distutils.spawn.find_executable might apply,

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.

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

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

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,
