## Overview

#### Purpose and Shape
This is a collection of standalone Python learning exercises with solutions, organized into two difficulty tiers. It is not an integrated application or package: each `.py` file is an independent executable example/problem solution.

#### Entry Points
Each problem file is a direct Python entry point, intended to be run individually with the Python interpreter. Representative files include:
- `Level_1_Python Program with solutions/Level_1_Problem_01.py`
- `Level_1_Python Program with solutions/Level_1_problem_27.py`
- `Level 2 Python Program with solutions/Level_2_Program_01.py`

There is no visible central launcher, importable application module, CLI dispatcher, or orchestration layer.

#### Level 1 Exercise Set
The primary beginner curriculum resides in `Level_1_Python Program with solutions/`. It contains numbered problem implementations, largely spanning 1–35:
- `Level_1_Python Program with solutions/Level_1_Problem_01.py`
- `Level_1_Python Program with solutions/Level_1_Problem_16.py`
- `Level_1_Python Program with solutions/Level_1_Problem_35.py`

Numbering is convention-based rather than enforced by a manifest; problem 27 uses a lowercase filename segment (`Level_1_problem_27.py`), which matters for case-sensitive paths.

#### Level 2 Exercise Set
More advanced exercises are isolated in `Level 2 Python Program with solutions/`, with programs numbered 1–16:
- `Level 2 Python Program with solutions/Level_2_Program_01.py`
- `Level 2 Python Program with solutions/Level_2_Program_08.py`
- `Level 2 Python Program with solutions/Level_2_Program_16.py`

This directory is a peer collection to Level 1, not a dependency layer or package extension.

#### Execution and Data Flow
The expected control flow is per-file: a user selects an exercise, executes its script, supplies any runtime input requested by that script, and receives output through the terminal. Inputs, intermediate values, and outputs are local to a single program invocation; no shared persistence, inter-problem data flow, or reusable domain model is evident from the repository layout.

#### Boundaries and Runtime
The material runtime is Python. The repository contains no dependency manifest, framework structure, container/deployment assets, database schema, API client layer, cloud infrastructure, or external-service integration. `README.md` is present but supplied without content, so the directory names and script naming establish the usable navigation and curriculum boundaries.

#### Maintenance Implications
Treat every numbered script as independently owned and runnable. Cross-cutting changes—such as a common runner, shared utilities, tests, or packaging—would be new architecture rather than modification of an existing platform. Preserve directory names with spaces and the Level 1/Level 2 separation because they are the repository’s effective organization and discovery mechanism.
