Question

I want to specify variable once by making instance Outer(variable), than this variable use in all static classes, how should I do that? Is there any other solution than use not static methods and pass Outer into each inner class?

class Outer():
    def __init__(self, variable):
        self.variable= variable

    class Inner1():        
        @staticmethod
        def work1():
            **print Outer.variable**

    class Inner2():        
        @staticmethod
        def work2():
            **print Outer.variable**

Answer 1

No. Inner-class methods have no way of accessing instances of the outer class.
