# Playwright examples using Python

Demonstration of:

• Playwright browser automation testing
• Python programming language
• Chromium open source web browser

Install

Install Python

Install Python from https://www.python.org/

Run this to confirm your version:

python --version

Output should be at least:

Python 3.13.3

Install Playwright

Install Playwright and whichever browsers you want:

pip install playwright
playwright install chromium 
playwright install firefox
playwright install webkit

Optional for type checking:

pip install mypy

Update

Run:

pip install --upgrade pip
pip install --upgrade playwright
pip install --upgrade mypy

Run

Run:

src/demo.py

If you prefer, you can run with python explicitly:

python src/demo.py

If you prefer, you can run with type checking:

mypy src/demo.py

The script will do three things:

1. Launch your local Chrome web browser to view the free open source testing examples web page https://testingexamples.github.io.

2. Interact with the web page in various ways, such as finding elements, clicking on elements, filling in form inputs, etc.

3. Print some typical HTML tag output that demonstrates the program is running successfully.

Additional Python Features

Async Alternative: a commented demo_async() function showing how to use the async API if needed.

Python Type Hints:

• Full type annotations for better IDE support
• Compatible with type checkers like mypy
• Optional but recommended for larger projects

Error Handling:

• Use traceback module for detailed error reporting
• Use sys.stderr for error output
• Use sys.exit(1) for proper exit codes
