Instead, use a compatible character encoding. Note the explicit conversion.

Alternatively, you can write sixteen bit unicode directly to a file:
import codecs
f = codecs.open('unicodetest.txt', mode='w', encoding='utf-16&

and it also defines g as a function that returns a generator.

B.py is the entry point of the program and it is known internally as
__main__. There is no record of a B.py.
If you really must import objects from the main module you can do it like
this.
from __main__ import *

Maybe use in conjunction with python-inotify and or Gamin for change

Which is not what the OP asked for. Anyway, I think whatever solution is
chosen it's probably best written as a generator. The new pushback syntax
may prove useful.

I hope this gives you some good ideas.
http://en.wikipedia.org/wiki/Join_(SQL)
I suspect you will be finding a use for the special __getattr__ method,
which is called when an attribute is not found. This can be used to search
on your set of joined objects. Your list of joined objects should be a
set() to prevent duplicates.
