+# Squirrel Census
 
+Day 25 of Udemy's *100 Days of Code: The Complete Python Pro Bootcamp*: count the
+squirrels of the 2018 Central Park Squirrel Census by primary fur colour (gray,
+cinnamon, black) and export the counts to `squirrel_count.csv`. Python 3.13 or
+later, no runtime dependencies, with tests and source documentation.
+
+![Program run][img-run]
+
+## Requirements
+
+- Python 3.13 or later (`python --version` on Windows, `python3 --version` on Linux and macOS).
+- `venv`, which ships with Python (on Debian: the `python3-venv` package).
+- The 2018 census file. It is already in the repository under `data/`.
+- Optional: [Doxygen][doxygen] 1.9 or later, only to build the source documentation.
+
+There are no runtime dependencies: the program uses only the Python standard library
+([ADR-0001][adr-0001]). `pytest` is needed only to run the tests.
+
+## Set up
+
+Create a local virtual environment named `.venv` in the project folder, upgrade `pip`
+and install the project with its development tools (pytest, ruff, mypy).
+
+### Windows powershell
+
+```powershell
+python -m venv .venv
+.\.venv\Scripts\Activate.ps1
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+If PowerShell refuses to run the activation script, allow it for the current session:
+`Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned`.
+
+### Linux debian
+
+```bash
+sudo apt install python3 python3-venv
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+### MacOS
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+On macOS, Python 3.13 can be installed with `brew install python@3.13`.
+
+## Run
+
+With the virtual environment active, run from the project folder:
+
+```bash
+python -m squirrel
+```
+
+The program reads `data/2018_Central_Park_Squirrel_Census_-_Squirrel_Data.csv`, prints
+the colour counts and writes `squirrel_count.csv`:
+
+```text
+Gray: 2473
+Cinnamon: 392
+Black: 103
+```
+
+Use other files by passing them as arguments, `python -m squirrel <census file> <summary file>`.
+If the census file does not exist the program prints a message and exits with status 2.
+
+## Run the tests
+
+```bash
+python -m pytest
+```
+
+![Test run][img-tests]
+
+The tests use small fixture rows; one test also checks the real 2018 census file when
+it is present.
+
+## Continuous integration
+
+The workflow [`.gitea/workflows/ci.yml`][ci] runs for every push to `main` and for every
+pull request. It sets up Python 3.13, creates a `.venv`, upgrades `pip`, installs the
+project with `.[dev]` and runs `python -m pytest`. It uses `github.*` contexts only, so
+it also runs on GitHub Actions.
+
+## Build the source documentation
+
+The source is documented with Doxygen comments and configured by [`Doxyfile`][doxyfile].
+
+```bash
+doxygen Doxyfile
+```
+
+Open `docs/doxygen/html/index.html` in a browser. The output folder is ignored by git.
+
+## Project layout
+

+| --- | --- | --- | --- |
+| 22 | Every workflow feature used is verified on the instance that runs it, and the host and version are recorded; a feature the target hosts differ on is noted in the header (Mandatory) | Pass | Gitea 1.27.3, runner labels ubuntu-latest. `ci.yml` completed with success on the instance: pull_request runs 1037, 1040 and 1043, and the push run 1044 on main (commit c4e88c6). Header states the host and that only github.* contexts are used. |
+
+## Overall Verdict
+
+Go — criterion 22, the only open Mandatory criterion of RC-010, now passes; the other rows of RC-010 still hold, so the workflow is Go. Closes the condition of RC-010.

+# Beskrivelse
+
+## Hvad programmet gør
+
+Programmet følger lektionens trin:
+
+1. `read_csv` læser optællingsfilen.
+2. `count_by_fur_color` tæller observationerne af Gray, Cinnamon og Black.
+3. `build_summary` gør tallene til rækkerne i en opsummering.
+4. `write_csv` skriver opsummeringen til `squirrel_count.csv`.
+
+På optællingsfilen fra 2018 er resultatet Gray 2473, Cinnamon 392 og Black 103. Observationer uden pelsfarve tælles ikke med i nogen af dem.
+
+## Hvorfor ikke Pandas
+
+Lektionen bruger Pandas. Dette projekt bruger kun Pythons standardbibliotek (`csv` og `collections.Counter`), så der ikke er noget at installere for at køre det. Beslutningen er beskrevet som ADR-0001 i repositoryet.
+
+## Opbygning
+
+| Sti | Indhold |
+| --- | --- |
+| `src/squirrel/census.py` | De fire trin ovenfor |
+| `src/squirrel/cli.py` | Kommandolinjen, `python -m squirrel` |
+| `src/squirrel/constants.py` | Alle konstanter, defineret ét sted |
+| `tests/` | pytest-testene |
+| `docs/` | Business case, plan, modeller, reviewposter |
+
+## Kvalitet
+
+Alle dokumenter og al kode er gennemgået mod tjeklisterne i SQA- og QC-frameworket i autonom tilstand: reviewer er en AI-stedfortræder, så reviewene er ikke uafhængige.

+# Description
+
+## What it does
+
+The program follows the steps of the lecture:
+
+1. `read_csv` reads the census file.
+2. `count_by_fur_color` counts the sightings of Gray, Cinnamon and Black.
+3. `build_summary` turns the counts into the rows of a summary.
+4. `write_csv` writes the summary to `squirrel_count.csv`.
+
+On the 2018 census file the result is Gray 2473, Cinnamon 392 and Black 103. Sightings without a fur colour are counted in none of them.
+
+## Why no Pandas
+
+The lecture uses Pandas. This project uses only the Python standard library (`csv` and `collections.Counter`) so that there is nothing to install to run it. The decision is recorded as ADR-0001 in the repository.
+
+## Layout
+
+| Path | Content |
+| --- | --- |
+| `src/squirrel/census.py` | The four steps above |
+| `src/squirrel/cli.py` | The command line, `python -m squirrel` |
+| `src/squirrel/constants.py` | Every literal, defined once |
+| `tests/` | The pytest tests |
+| `docs/` | Business case, plan, models, review records |
+
+## Quality
+
+Every document and every piece of code was reviewed against the checklists of the SQA and QC framework, in autonomous mode: the reviewer is an AI stand-in, so the reviews are not independent.

+# Penerangan
+
+## Apa yang dilakukan program
+
+Program mengikut langkah dalam pelajaran:
+
+1. `read_csv` membaca fail banci.
+2. `count_by_fur_color` mengira pemerhatian Gray, Cinnamon dan Black.
+3. `build_summary` menukar kiraan kepada baris ringkasan.
+4. `write_csv` menulis ringkasan ke `squirrel_count.csv`.
+
+Pada fail banci 2018 hasilnya ialah Gray 2473, Cinnamon 392 dan Black 103. Pemerhatian tanpa warna bulu tidak dikira dalam mana-mana satu.
+
+## Mengapa tidak menggunakan Pandas
+
+Pelajaran menggunakan Pandas. Projek ini hanya menggunakan pustaka standard Python (`csv` dan `collections.Counter`) supaya tiada apa-apa untuk dipasang bagi menjalankannya. Keputusan itu direkodkan sebagai ADR-0001 dalam repositori.
+
+## Susun atur
+
+| Laluan | Kandungan |
+| --- | --- |
+| `src/squirrel/census.py` | Empat langkah di atas |
+| `src/squirrel/cli.py` | Baris perintah, `python -m squirrel` |
+| `src/squirrel/constants.py` | Semua pemalar, ditakrif sekali |
+| `tests/` | Ujian pytest |
+| `docs/` | Kes perniagaan, pelan, model, rekod semakan |
+
+## Kualiti
+
+Setiap dokumen dan kod disemak berdasarkan senarai semak rangka kerja SQA dan QC dalam mod autonomi: penyemak ialah pengganti AI, jadi semakan itu tidak bebas.
