Outer, Inner, and Local Variables Dry Run in PYTHON

Outer, Inner, and Local Variables is an interactive PYTHON dry run visualizer from the Nestedclass programs section. Study the source code, then use the execution controls to follow each step, variable update, highlighted line, and console output.

This page provides a browser-based dry run with source-code highlighting, auto-scroll, voice narration controls, and execution output for learning the program step by step.

Outer, Inner, and Local Variables Program Code

class Outer:
    a = 12

    class Inner:
        a = 120

        def inner_method(self):
            a = 1200
            o1 = Outer()
            print("Outer class variable:", o1.a)
            print("Inner class variable:", self.a)
            print("Inner method local variable:", a)


i1 = Outer.Inner()
i1.inner_method()
