# 🚀 scrape-movies # 🚀 scrape-movies
Day 45 of Udemy's "100 Days of Code: The Complete Python Pro Bootcamp": web scraping with Requests and BeautifulSoup. It parses a local HTML page, scrapes the Hacker News front page and writes Empire's 100 greatest movies to `movies.txt`. It is for fellow coursists and anyone looking for a small, tested scraping example.

## 🛠️ Setup ## 🛠️ Setup
Create a local virtual environment named `.venv`, update `pip`, then install the project with its test tools. Create a local virtual environment named `.venv`, update `pip`, then install the project with its test tools.
Windows (PowerShell): Windows (PowerShell):
```powershell ```powershell
python -m venv .venv python -m venv .venv
.venv\Scripts\Activate.ps1 .venv\Scripts\Activate.ps1
python -m pip install --upgrade pip python -m pip install --upgrade pip
python -m pip install -e ".[dev]" python -m pip install -e ".[dev]"
``` ```
Linux and macOS: Linux and macOS:
```bash ```bash
python3 -m venv .venv python3 -m venv .venv
source .venv/bin/activate source .venv/bin/activate
python -m pip install --upgrade pip python -m pip install --upgrade pip
python -m pip install -e ".[dev]" python -m pip install -e ".[dev]"
``` ```
Leave out `[dev]` to install only the runtime dependencies. Personal tokens belong in a git-ignored `.env`; the project never reads it. Leave out `[dev]` to install only the runtime dependencies. Personal tokens belong in a git-ignored `.env`; the project never reads it.
## ▶️ Run ## ▶️ Run
The lecture steps are added milestone by milestone; each gets a section with its command, its output and a screenshot here. Every lecture step is a command of the form `python -m scrape_movies <lecture> <step>`; without arguments the help is printed. Each step below shows the command, what it teaches and a screenshot of its output.
```bash ### Lecture: Parsing HTML and making soup
python -m scrape_movies # available from the movies milestone
``` The sample page is `tests/fixtures/website.html`; the code is `src/scrape_movies/infrastructure/soup_basics.py`.
## 🧪 Tests **1. Create a soup and read the title** (`BeautifulSoup(html, "html.parser")`, `soup.title.string`)
```bash ```bash
python -m pytest python -m scrape_movies soup title
``` ```
The tests use saved pages and never touch the network. Lint and types: `ruff check .`, `ruff format --check .` and `mypy src tests`. API pages: `doxygen Doxyfile`. ![Step 1: soup title](docs/images/soup-1-title.png)
## 📄 License **2. Prettify** (`soup.prettify()` indents one tag per line)
See [LICENSE](./LICENSE). ```bash
python -m scrape_movies soup prettify

- [Issue tracker][issues] **3. Find all tags** (`find_all("a")`, then `get_text()` and `get("href")` in a loop)
