Dear all,
I need to write integer values to a binary file that will be read by
another application, specifically ENVI. I want to write these values
without intervening spaces between values. For example:
My data is a = [23, 45, 56, 255].
My desire output is: 234556255, of course in binary file

Hi,
I'm reading the Python Reference Manual in order to gain a better understanding
of Python under the hood.
On the last paragraph of 3.1, there is a statement on immutable and mutable

I have a string a = "['xyz', 'abc']".. I would like to convert it to a

Sure enough, passing shell=True -- which is probably quite
a rare requirement -- causes the code to change the

It seems the development of Cython is going very well, quite
differently from the dead-looking Pyrex. Hopefully Cython will become
more user-friendly too (Pyrex is far from being user-friendly for

Their efficiency is mostly regarding the space. I think they aren't
much speed-efficient because they require many conversions from-to
Python types.
You can gain speed efficiency too (sometimes a LOT), in some
situations, using array with Psyco.
Another advantage of arrays (better called "vector"s,

I believe the array module provides more functionality than lists.
Perhaps this extra functionality comes with... overhead? C'est possible.
For example, you can declare an array to contain all items of a type, ie:
>>array.array('f')#array of floats
So, they might be efficient, in that they'r

Sorry I don't have much of a better idea, but if I had this kind of problem
with an RPM, I'd just grab the tarball and start hacking away at ./configure
pre-requirements, trying to use --options to trim it down to the bare
minimal and see if I can get it to load up.

Hi,
For those on several python lists, I appologize in advance for
cross-posting, but I'm really not sure which list is best to ask for
assistance with this.
Currently, I am trying to build the python2.4 SRPM from Python.org on a
RHEL4 x64 platform, but the build is failing with a very non-descri
