intricated functions: how to share a variable

Thanks for your answer.
Yes, it is better like this. My problem is that I cannot get the return
values of the function and affect it to some variable, because the function
is called via a "signal-slot" connection of PyQt4, not by an explicit
inline function call.

For example:
#########
def tutu():

    def toto():

        print a
        a = 4
        print a

    a=2

    # ...
    # definition of some graphical QPushButton "button"
    # ...
    # ...

    self.connect( button, SIGNAL( "clicked" ), toto )

tutu()
##########

Then, as advised Diez, perhaps the best solution is to have "true" global
variables by using a class and defining the variable a as a member self.a
of the class. By doing like this, a will be known everywhere.
