I am new to Python, having perviously used IDL for all my scripts.
I was hoping to use Python and so I have just downloaded and
installed
version 2.6 using the mac installer. That all went fine.

I use codecs to retain consistent unicode/utf-8 encoding and decoding for
reading/writing to files. Should the codecs be applied when using the
pickle/unpickle function? For example, the standard syntax is:
# pickle object

pickle.dump(object, f, 2)
# unpickle object

You don't.
What does "put two strings into 1 string" mean. Provide an example.
What does the documentation say about join? What part of that do you not

Oke,

Dear Tutors,
I noticed that when you use a property to represent a mutable
value, I you try to use its methods, it will directly change the value
returned. I know this happens because I'm not really assigning it to
something new, but changing whats already there, which won't fire off
