Mathematical Model
Theory & Governing Equations
Analytical principles modeled in this interactive visualizer:
Stack → Pointer → Heap Object(Type, Value, id)
Key Exam Concepts:
- In Python, variables are named references (pointers) stored on the call stack that point to allocated objects in heap memory.
- Immutable types (int, float, str, tuple) allocate new heap objects on reassignment.
- Mutable objects (list, dict, set) can be modified in-place without altering their memory address
id().
