You need to declare _expensiveObject as global inside your function.
Whenever you assign something to a variable that resides in the global
scope inside a function, you need to declare it as global at the
beginning of the function. So your function should look like this
def ExpensiveObject():
List:
I've a module that's not doing what I expect. My guess is that I don't
quite understand the scoping rules the way I should.
I have an object that's costly to create. My thought was to create it
at the module level like this:
# expensive Object Module
_expensiveObject = None
def Expensiv
