TWELVE TIERS. ONE CIRCUIT.
A sequential mastery path is being built — each tier gated behind the last, earned rather than skipped. Until it opens, the complete theory lives in Modules, ready now.
Algorithmic Thinking & Setup
Master algorithms, pseudocode logic, variable bindings, primitive types, operators, and PEP 8 code formatting.
Control Flow & Functions
Master selection logic (if/elif/else), iteration loops (for/while), break/continue, and function definitions.
Collections & Debugging
Master sequence data structures: mutable lists, immutable tuples, unicode strings, slicing, and PDB debugging.
Dictionaries, Sets & Libraries
Master O(1) hash table dictionaries, unique set collections, standard library modules, and complete Assessment Checkpoint 1.
Functions Deep Dive
Master positional/keyword parameters, *args, **kwargs, LEGB scope resolution, and unittest frameworks.
Exceptions & Recursion
Master exception hierarchies, custom exception classes, recursive call stacks, and base-case termination rules.
Modules, Packages & Files
Master module import paths, `__init__.py` package namespaces, context managers (`with`), and file stream I/O.
Practice & Mastery
Freeform interactive Playground sandbox, ungated Appendix reference documentation, comprehensive practice problem sets, and Assessment Checkpoint 2.
