get yourself an editor that is Python-aware (Emacs, PythonWin, Scite,
etc.). It will let you increase or decrease the indentation of a block
of code easily. Then you will be spared the finger gymnastics of typing
all those darn braces and semicolons!

Maybe, but the idea of a module as a storage place for an assortment of
data that you want to access from lots of places is a good one. Those
FORTRAN common blocks were good for something, you know! Just be careful
about over-using it. I tend to reserve it for things that are only set
once, and then only read by various other modules later, if a piece of
data is being changed by a lot of different modules, it may not belong
there.
As far a OO design is concerned, a module used in this way is very much
like a class with only one instance. It's just a little less code. IN
fact, it may make sense to put accessor functions in your globals
module, like:
globals.getUserList()
rather than explicity accessing the global value itself.
