Why Does obj.method() Automatically Receive self? A Deep Dive into Python Method Binding
A clear explanation of Python’s method binding rules—how the descriptor protocol governs attribute access, and why calling an undecorated method via the class (e.g., ClassName.method(arg1, arg2)) does not involve instance binding.
Python learners and contributors often encounter confusion around why methods without decorators behave differently depending on how they’re accessed. This project clarifies the mechanism by tracing the actual descriptor protocol (__get__) and showing exactly how Python transforms functions into bound or unbound callables.
