The simplest complex example that I can think of to show main Flask app concepts.
The first example is app.py. In this example, I show you how to embed a pandas.DataFrame() table inside an HTML page served up using Flask.
Key concepts here:
- Jinja2 templating: (
{{ variable_name }}syntax) - Template inheritance: (
{% extends "parent.html" %}) - Styling with Bootstrap CSS
- Marking strings as safe to render: (
{{ string|safe }})
The second example is display_bokeh.py. In this example, I show you how to embed a Bokeh plot on an HTML page served up using Flask.
Key concepts here:
- Marking strings as safe to render (see above)
- Refactoring granular logic into a utility function, so that only application "business logic" remains.
