In general, no. If you simply want to use it, then assigning
to it once at the module level is sufficient. If you want to
assign to it in various functions, you have to tell Python
that it isn't local, by using a global statement in the
function.

However, you can sidestep the issue by defining
an accessor function. That is, you can define
a function whose sole purpose is to set the variable.
That can be accessed globally, so you don't have to
declare the variable in each function where you want
to modify it.
