A flash card program for learning the most frequent Malay words with their Danish translations. It is the solution of day 31 of Udemy's 100 Days of Code: The Complete Python Pro Bootcamp, written for course participants who want to compare solutions and for visitors who browse the repository for ideas.

🧭 Overview

The program shows a Malay word on a card. After three seconds the card turns over and shows the Danish translation. You press the green tick when you know the word and the red cross when you do not. A known word is removed from the words to learn, and the words still to learn are saved, so the next start continues where you stopped.

Part	What it is for
`src/flash_card/`	The program, in four layers: `domain`, `application`, `infrastructure`, `presentation`
`tests/`	`pytest` tests: `unit`, `integration`, `e2e`
`data/`	The word list `ms-da.csv` and, after the first known word, your own `words_to_learn.csv`
`docs/`	Project documents (business case, plan, design, review records)
`Doxyfile`	Doxygen configuration for the source code documentation

The core program uses only the Python standard library. Spoken Malay words are an optional extra.

📋 Requirements

Need	Why
Python 3.13 or later, with Tkinter	The program and its window (Tkinter is part of the standard Python installers for Windows and macOS; on Debian or Ubuntu install `python3-tk`)
`git`	To clone the repository
Doxygen (optional)	To build the source code documentation
`gTTS` and `playsound==1.2.2` (optional, extra `speech`)	To hear the Malay word; needs a network connection

🛠️ Setup

Create a virtual environment in .venv, activate it, upgrade pip and install the project. Run the commands in the repository folder.

Windows (PowerShell):

python -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip
python -m pip install -e ".[dev]"

Linux and macOS:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -e ".[dev]"

Use python -m pip install -e . if you only want to run the program; the dev extra adds pytest, ruff, mypy and import-linter.
Add the spoken word with python -m pip install -e ".[speech]".
If PowerShell refuses to run Activate.ps1, run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or use .\.venv\Scripts\activate.bat in cmd.
Leave the environment with deactivate. Delete the .venv folder to start over.

▶️ Run

python -m flash_card

The program is run from the activated .venv. The window opens with the first card; the program is built step by step and the pull requests and milestones show each step.

🧪 Tests

python -m pytest

Quality checks used by the project:

python -m ruff check src tests
python -m mypy
lint-imports

The window test in tests/e2e/ is skipped when no display is available.
