Lecture 2: URL paths
Code: src/higher_lower/presentation/lectures/step_02_url_paths.py.
What we gained
- A route is a function bound to a URL path with
@app.route. - A variable section such as
/username/<name>passes the text of the URL to the function. - A converter such as
<int:number>checks the type; other text gives a 404 page. - Debug mode reloads the server on every change and shows the Flask debugger with the values of the variables when an error happens.
- User text in a page must be escaped, so the code uses
escape.
