Hello
I am new to python programming. while trying it out i find that in my
code file io.read is not reading large files particularly over 1 gb. my
code is posted below. i am working on python 3.3 on windows with ntfs
partition and intel corei3 ram 3gb. the execution always stops saying
error
Hi All:
I am a newbie at the Python.
I type "26/12" in Python Console and get result of "2".
It is obvious that the corresponding result should be 2... I don't
know why the Console only returns the integer part of true result. Anyone
can help me out?
Thanks
David

Thanks very much Alan. As for the my concern about inaccuracy in float math, I
suppose I am concerned because I was not aware of the issue before, and I
wonder how you deal with such things when you need accuracy for financial

Financial applications traditionally work in the lowest unit of currency and
use integers.
For display purposes they convert the pennies into dollars/cents or

Hi,
from the question you're using python 2.x
you can do either: 26.0/12 (float divide by int - it retypes both to
floats and gets you 2.)
or at the beginning do:
from __future__ import division
That will activate python3 way of dividing - which gives you 2.
Lukas.

No you are not.
You are importing it and then trying to access something called start
which doesn't exist.
