Hello, first off I am using Python 3.2 on Linux Mint 12 64-bit.
I am confused as to why I can not successfully compare a variable that
was created as an octal to a variable that is converted to an octal in a
if statement yet print yields that they are the same octal value. I
think it is because the

OK, Here is an attempt to explain the explanation!
Original question:
Why does -17 / 10 => -2 instead of -1

Thank you for the detailed answer, now I understand and I understand
that each number format is an integer just with a different base and
cosmetic appearance.

Steven has already answered your issue but just to emphasise
this point.
Python stores all data as binary values in memory. Octal,
decimal, hex are

Integer division with negative numbers can be done in two different ways.
(1) 17/-10 gives -1, with remainder 7.
Proof: -1 times -10 is 10, plus 7 gives 17.
(2) 17/-10 gives -2, with remainder -3.
Proof: -2 times -10

Please don't do that. This risks becoming slow. REALLY slow. Painfully slow.
Hi,
I want to use difflib to compare a lot (tens of thousands) of text files. I

Thanks for the excellent feedback and very informative. I guess I just
did not consider the memory side of things and did not think about just
how much extra addition was having to occur.
Additionally I also found this supporting link:
