# 055-higher-lower
# 🚀 Higher or Lower
Day 55 of Udemy's *100 Days of Code: The Complete Python Pro Bootcamp*: a Higher or Lower guessing game as a Flask website, written for fellow course participants and for anyone who browses the repository for ideas.

## 🧭 Overview
The site picks a secret number between 0 and 9. Open `/` for the start page, then guess by putting a number in the URL, for example `/3`. The page tells you whether the guess is too low, too high or correct, with a different heading colour and GIF for each answer.
The repository also holds the small Flask programs of the day's lectures: URL paths, rendering HTML and decorators.
| Part | What it is for |
| --- | --- |
| `server.py` | Starts the game, as the assignment asks |
| `src/higher_lower/` | The game, split in layers: `domain`, `application`, `infrastructure`, `presentation` |
| `src/higher_lower/constants.py` | Every heading, colour, GIF and number range in one place |
| `tests/` | pytest tests |
| `docs/` | Project documents (business case, plan, milestones, reviews) |
| `Doxyfile` | Settings to generate API documentation with Doxygen |
## 📋 Requirements
- Python 3.13 or later, to run the code.
- Flask, the only runtime dependency, installed by the setup below.
- pytest, to run the tests (installed with the `test` extra).
- Doxygen, only if you want to generate the API documentation.
## 🛠️ Setup
Create a local virtual environment named `.venv` in the project folder, activate it, upgrade pip and install the project.
Windows (PowerShell):
```powershell
python -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip
python -m pip install -e ".[test]"
```
Linux and macOS:
```bash
python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -e ".[test]"
```
While the environment is active, the prompt starts with `(.venv)`. Leave it with `deactivate`. Delete the `.venv` folder to start over.
## ▶️ Run
```bash
python server.py
```
Open `http://127.0.0.1:5000/` in a browser, then try `http://127.0.0.1:5000/3`.
## 🧪 Tests
```bash
python -m pytest
```
Generate the API documentation with Doxygen into `build/html`:
```bash
doxygen Doxyfile
```

## Version History
| Date | Status | Author | Reviewer | Change | Commit |
| --- | --- | --- | --- | --- | --- |
| 2026-11-06 | Accepted | Jens Tirsvad Nielsen | AI as stand-in for S01 | Initial version | [42b3a09] |
---
## Purpose
This plan schedules the four phases that deliver the Higher or Lower Flask project within the few-day effort stated in [BC-001]. S01 is the Product Owner and owns every phase; [SA-001] sets the cadence: one reviewed pull request per phase.
## Planning Assumptions
- Week 1 starts 2026-11-06; the plan ends by 2026-11-16, the few-day effort of [BC-001] Constraints; the dates are the planner's estimate, accepted by S01 in chat on 2026-11-06.
- Phase length: two to three days each; one branch and one pull request per phase.
- Autonomous mode: the AI acts as stand-in reviewer for S01 and every review record says so.
- The Milestone column stays blank (not yet synced) until the host sync runs.
- Tokens come from `.env`, which is ignored by git and never imported by the project.
## Gateway Schedule

| Project setup | [MIL-001] | 2026-11-06 to 2026-11-08 | 2026-11-08 | S01 | none (technical tasks) | Skeleton, tooling, README, repository metadata | |
| Lecture steps | [MIL-002] | 2026-11-08 to 2026-11-10 | 2026-11-10 | S01 | none (technical tasks) | Routes, HTML and decorator modules with tests | |
| Higher or Lower game | [MIL-003] | 2026-11-10 to 2026-11-12 | 2026-11-12 | S01 | none (technical tasks) | The final project with tests | |
| Docs, screenshots and wiki | [MIL-004] | 2026-11-12 to 2026-11-16 | 2026-11-16 | S01 | none (technical tasks) | Screenshots, README, wiki in en, da, ms | |

## Scope Coverage
| Business Case scope item | Gateway |
| --- | --- |
| Flask application in `src/`, tests in `tests/` | MIL-002, MIL-003 |
| `constants.py`, `pyproject.toml`, `.gitignore`, Doxygen comments, `Doxyfile` | MIL-001 |
| README from the framework template | MIL-001, MIL-004 |
| Screenshots and wiki in en, da, ms | MIL-004 |
| Repository description and topics | MIL-001 |
## Dependencies
```
MIL-001 → MIL-002 → MIL-003 → MIL-004
```
A No-Go on a phase stops the later phases; their dates and the end date move by the length of the rework, and S01 decides the move.
## Plan Risks
| Risk | Impact | Mitigation |
| --- | --- | --- |
| Docker Desktop is not running on the host, so screenshots cannot be taken in a container (BC-001 risk: screenshots need a browser) | MIL-004 blocked | Start Docker Desktop, or use Windows Sandbox; stop and report if neither is available |
| The three-language wiki takes longer than planned (BC-001 risk: translation errors in da or ms) | MIL-004 slips | Keep pages short and structurally identical |
## Open Issues
- The user named `https://git.tirsystem.com/Tirsvad-Udemy-100_days_of_code`; `origin` points at `Tirsvad-Udemy-100-days-of-code/055-higher-lower`. The plan uses `origin`; S01 can correct this at plan acceptance.
- The tasks are plain technical tasks with no use case, because the assignment text is the specification; a use case is added if the reviewer asks for one.
- The wiki is written as files in the repository (`docs/wiki/en`, `da`, `ms`) and published to the host wiki only if the host exposes it.

## Scope Coverage
| Business Case scope item | Gateway |
| --- | --- |
| Flask application in `src/`, tests in `tests/` | MIL-002, MIL-003 |
| `constants.py`, `pyproject.toml`, `.gitignore`, Doxygen comments, `Doxyfile` | MIL-001 |
| README from the framework template | MIL-001, MIL-004 |
| Screenshots and wiki in en, da, ms | MIL-004 |
| Repository description and topics | MIL-001 |
## Dependencies
```
MIL-001 → MIL-002 → MIL-003 → MIL-004
```
A No-Go on a phase stops the later phases; their dates and the end date move by the length of the rework, and S01 decides the move.
## Plan Risks
| Risk | Impact | Mitigation |
| --- | --- | --- |
| Docker Desktop is not running on the host, so screenshots cannot be taken in a container (BC-001 risk: screenshots need a browser) | MIL-004 blocked | Start Docker Desktop, or use Windows Sandbox; stop and report if neither is available |
| The three-language wiki takes longer than planned (BC-001 risk: translation errors in da or ms) | MIL-004 slips | Keep pages short and structurally identical |
## Open Issues
- The user named `https://git.tirsystem.com/Tirsvad-Udemy-100_days_of_code`; `origin` points at `Tirsvad-Udemy-100-days-of-code/055-higher-lower`. The plan uses `origin`; S01 can correct this at plan acceptance.
- The tasks are plain technical tasks with no use case, because the assignment text is the specification; a use case is added if the reviewer asks for one.
- The wiki is written as flat files in `docs/wiki/` (English `Page.md`, Danish `Page-da.md`, Bahasa Malaysia `Page-ms.md`), as `framework/process/wiki.md` requires; the framework workflow publishes it to the host wiki after merge.

# RC-008 Code review of MIL-001
## Metadata
| Key | Value |
| --- | --- |
| ID | RC-008 |
| CrossReference | [MIL-001], [QC-PY-001] |
## Version History
| Date | Status | Author | Reviewer | Change | Commit |
| --- | --- | --- | --- | --- | --- |
| 2026-11-06 | Accepted | Jens Tirsvad Nielsen | AI as stand-in for S01 | Initial version | [5ebc1df] |

## Artifact Under Review
- Instance reviewed: [MIL-001]
- Checklist used: [QC-PY-001]
- Scope: Code of MIL-001: `src/higher_lower/constants.py`, layer packages, `tests/unit/test_constants.py`, and the project configuration
- Language and domain: n/a (technical type)
- Language reviewer: none
- Mode: autonomous, not independent (the reviewer is `AI as stand-in for S01`)
## Checklist Results
| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) | Pass | Modules and functions use snake_case, classes PascalCase, constants UPPER_SNAKE |
| 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes | Pass | Names state purpose (`compare_guess`, `GuessResult`, `HOME_HEADING`); no unexplained abbreviations |
| 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions | Pass | `ruff check` and `ruff format --check` report no finding; no suppressions |
| 4 | Every function and method signature is type-annotated, including `-> None` | Pass | Every signature is annotated; `mypy --strict` reports no issue |
| 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) | Pass | No bare `except`; no exception is swallowed |
| 6 | No mutable default arguments and no shadowed builtins | Pass | No mutable default arguments; no builtin is shadowed |
| 7 | Files, locks and connections are managed with context managers | N-A | The code opens no file, lock or connection |
| 8 | Public modules, classes and functions have docstrings that say what, not how | Pass | Public modules, classes and functions have Doxygen-style docstrings |
| 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output | Pass | No `print`; no secret in the code; `.env` is neither read nor imported |
| 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded | N-A | No DCD exists: the milestone tasks are plain technical tasks (see PP-001 Open Issues) |
| 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network | Pass | pytest tests are named for behaviour, run in any order and use no network |
| 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment | Pass | `mypy --strict` passes; no `Any` |
| 13 | Dependencies are declared and pinned in the project's dependency file, none unused | Pass | `pyproject.toml` declares Flask (runtime) and pytest, ruff, mypy (extras); none unused |
| 14 | Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike | Pass | Headings, colours, GIFs and range are defined once in `constants.py` |
| 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles | Pass | Only `constants.py` exists; it imports nothing |
| 16 | SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations | Pass | Each module has one reason to change; behaviour is added by extension |
| 17 | Source is laid out in the layers and folders of the clean architecture folder structure (`domain`, `application`, `infrastructure`, `presentation` packages under `src/`, and `unit`, `integration` and `e2e` under `tests/`), in `snake_case`, and imports between the layers point inward | Pass | The four layer packages exist under `src/higher_lower/`; tests are under `tests/unit`; the layers are filled by MIL-003 |
| 18 | File and folder names are English, contain no space and no character outside letters, digits, `-`, `_` and `.`, and follow the casing of the language for files | Pass | File and folder names are English with letters, digits and `_` only |
## Overall Verdict
Go — All criteria pass or are not applicable; no blocking finding.
