Hi,
I am trying to represent a number as a list of bits: for example the bit
representation of the integer 8. I did find a number of articles
pertaining to a module called bitarray but I was unable to
download/install that package. I am using Linux on Ubuntu 9.10; Python
2.6.2.
I am almost certa

Wayne,
Thank you very much.

My approach has been to store it as an array and then build the integer as
needed. This code requires Python 2.5 or later.
def bits2int(l):
return sum([2**i if j else 0 for i,j in enumerate(l)])
To convert the other way:
def int2bits(m, n):
return [int(bool(m&(1<>= inc
return i

I don't know that you will reach Mark through this list, I forwarded
his post from another list. There is some info on the book web site:

i believe the 1st ed is 3.0 and the 2nd ed is 3.1 but haven't

As`Kent Johnson pointed out, you don't need to convert anything to strings, etc.
An integer _is_ a bit array, and individual bits can be tested using the bitwise
operators. For your example, if A is an integer you can test bit 8 with:
if A & (1 << 8): dosomething
There is a simple example on the Py

Numbers are already represented as arrays of bits, thats how
they are stored.

I bought the 1st edition which is definitely 3.0.

Using an array of 32 bit integers, you have to go to some
trouble to slice out, say, bits 20 to 40.
I think I agree -- if in fact it's not impossible. Tell me that's a
typo or take a moment to explain what I'm misunderstanding...

Emille,
I do think he meant bit 20 to 32 rather than 20 to 40. Unless, of
course, he's dealing with a 64 bit word.
I am delighted with all the help I have received on this topic and I am
gleefully learning anding and oring, but not too much on the EOR side.
Thanks again for all the assistance.
