🚀 Birthday Wisher
Sends a random birthday letter by e-mail to everyone in birthdays.csv whose birthday is today. It is the "normal" level of day 32 of Udemy's 100 Days of Code: The Complete Python Pro Bootcamp, written for course participants and for anyone who browses the repository for ideas.
📚 Table of Contents
🧭 Overview
The program reads birthdays.csv, compares today's month and day with each row, picks one of letter_templates/letter_1.txt to letter_3.txt at random, replaces [NAME] with the person's name and sends the letter through SMTP with STARTTLS (Gmail by default). It uses only the Python standard library, so it has no runtime dependencies.
| Path | What it is |
|---|---|
src/birthday_wisher/ |
The program: domain, application, infrastructure and presentation layers, constants in constants.py |
tests/ |
pytest tests: unit, integration, e2e; all run offline |
birthdays.csv |
The people: name,email,year,month,day (dummy data) |
letter_templates/ |
Three letters with the [NAME] placeholder |
Doxyfile |
Doxygen configuration; the source carries Doxygen comments |
docs/ |
Project documents, images and the wiki in English, Danish and Bahasa Malaysia |
📋 Requirements
- Python 3.13 or newer, to run the program and the tests.
- A Gmail address and an app password, only to send real e-mail. A dry run and the tests need neither.
- Doxygen, only to build the API documentation (optional).
🛠️ Setup
Create and use a local virtual environment, then upgrade pip and install the project with its test tools:
python -m venv .venv
Activate it. On Windows (PowerShell): .venv\Scripts\Activate.ps1. On Windows (cmd): .venv\Scripts\activate. On Linux and macOS: source .venv/bin/activate.
python -m pip install --upgrade pip
python -m pip install -e ".[dev]"
To send real e-mail, set two environment variables (see .env.example; never commit a real .env):
export GMAIL_ADDRESS="you@gmail.com"
export GMAIL_TOKEN="your-app-password"
On Windows PowerShell use $env:GMAIL_ADDRESS = "you@gmail.com" and $env:GMAIL_TOKEN = "your-app-password".
▶️ Run
Print the letters instead of sending them (pretend today is 17 October 2000):
python -m birthday_wisher --dry-run --today 2000-10-17
Send the letters for today's birthdays:
python -m birthday_wisher
Options: --dry-run, --today YYYY-MM-DD, --csv FILE, --letters FOLDER. The program exits with status 1 when setup is wrong or a letter could not be sent. Generate the API documentation with doxygen Doxyfile (output in docs/doxygen/).
🧪 Tests
python -m pytest
The tests use a fake SMTP connection and temporary files. They need no network, no .env and no credentials.
