Confusion About Classes

[flamesrock]

Well, I took a short excursion into xml for a different part of the
program, but the class is now finished!! (source below) I have a few
more questions for you guys.

1)If I set
self.serverConfig = file(os.path.join('configuration','score.conf'),
'w')
and then go self.serverConfig.close(), is there a way to open it in
read mode without calling the filename directly? Like
self.serverConfig.open('r') -which doesn't work BTW- instead of
open(os.path.join('configuration','score.conf'), 'r')? Using
open(self.ServerConfig, 'r') doesn't seem to work either.

2) A problem arose when converting the encoded file back into a string
for decoding; the \n's seemed to have dissapeared so it returned an
error when I tried to decode. Is there a way to stop python from
disposing of those those characters before writing to file?

3) Is there way to retrieve the timestamp of a file via ftp?

Ahhhhh...now *that* makes sense. So dynamically typed variables aren't
variables at all...but just another term for pointers? cool, I like
that. And thanks for the examples, guys. Its coming together and I'm
starting to actually 'get it' :)

So name mangling basically follows the rules of private and public in
Java? (I have limited experience in java so don't quote me on that.)

(Google groups isn't displaying the spaces correctly, so I added four
*'s = 1 four space indentation..)
