Hi,

basic stuff that I needed to do, manipulating config files.

Yes
Names are handles for objects. Assignment binds
a name to an object. The same object can be
bound simultaneously to many names.

Thanks to everyone for the help. My coworker seems to really prefer
doing it via some system call.
She seems to think it's possible quickly with csplit, which I've never
used. I'll be investigating it in the morning, because she's really
good at what she does. :)

i'm guessing this is the "post-it effect".
aa = range(0,10)
print aa
[0,1,2,3,4,5,6,7,8,9]

Python lists are mutable. All mutable objects will behave in the fashion you
described, whereas immutable objects -- tuples, integer, floats, etc. --
will behave in the fashion that you expect.
This is because python keeps references to objects. When you say bb = aa,
you are really saying, "Ta

Paramiko rocks. I have a deployment system that works on linux, osx,

This is bill's method written out in code which is the python you seek,
young warrior!
inname = 'inputfile'
outname = 'outfile'
infile = open(inname,'r')
outfile = open(outname,'w')
infile.readline()
line = infile.readline()
while line != "":
outfile.write(line)
infile.close()
outfile.close()

I must be missing some simple method on a file object or something.
What I need to do is to truncate the first line of a file which has an
unknown number of lines and an unknown size.
The only thing I can think to do is to readlines() and then slice off
the first line in the resulting list, then

I am currently working on a raycasting engine using pygame for graphics. The
engine works great and now I'm thinking about adding support for textures.
The problem is that I'm not really sure to with modules and methods to use.
I need to be able to load textures, scale then to fit an

I have a webfaction server (highly recommended btw) and I'm trying to
use automate some tasks over ssh but I'm not having much luck with
pyssh http://pyssh.sourceforge.net/ .
Some of the docs mention methods that don't exist in the version I
downloaded, such as pyssh.run.

Finally got it working. I used your suggestion Rui, but I also had to
change the charset encoding that my database was using. Changed from
Latin-1 to UCS2.
I read http://www.joelonsoftware.com/articles/Unicode.html too.
Essential reading.
Thanks.
