Re: Please Explain This Error

The easiest way to do something like this is to have a class that you
create, then reference the variable in the class as in:

class foo:
    myvariable = 12

from foo import myvariable
class why:
    def printmyvariable(self):
      print myvariable

This is psuedo code that I have not tested. You had mentioned that you
couldn't import the other file because of circular dependencies. Now, my
python is rather primative myself, I have only been working with Python
for 2 years, so I still struggle sometimes with best ways and only one
way of doing things :)

Liam,

   I've gone around this error by moving the two database functions
(open and
close) into a separate module/class. Since that class is now imported by
all
the other modules that need database access, I'm trying to learn how to
make
a variable defined in one module -- the name of the database file --
visible
to the functions in the new module.

   This variable -- projname -- is local to the wxPthon text entry
function,
global to the MainFrame class, and not a built-in variable. Therefore,
it
is not visible to the openDB() and closeDB() functions in a completely
separate module. I'm trying to learn the python equivalent of C's
'extern'
declaration modifier.

Thanks,

Rich
