shiny-python-workshop-2023

This is the repository for the 2023 Shiny for Python workshop.

Installation

You will need to install a few things to render the website locally:

1) Install quarto 2) Install the shinylive python package pip install shinylive --upgrade 3) Install the shinylive quarto materials quarto add quarto-ext/shinylive

How to edit the materials

This is a quarto website, so to make changes to the course text modify the .qmd files, or the _quarto.yml. To do a live preview run quarto preview --render html, note that while --render html is a bit slower, it's the best way to see changes with the included applications.

Creating an including Shiny Apps

All of the apps live in the apps folder, which means that you can use VS Code to edit and test them out. To include an application insert an asis quarto chuck which looks like this:

#| echo: false
#| output: asis

include_shiny_folder("apps/basic-app")

You can also pass optins to this function to modify the behaviour of the included app.

To include a set of problem tabs, your app should have two application files. app.py which shows the starting point for the problem and app-solution.py which shows the target application. You can then use the problem_tabs function to include the tabs.

#| echo: false
#| output: asis

problem_tabs("apps/basic-app")

Inserting multiple choice questions

You can insert a shinylive app which displays sets of multiple choice questions by supplying a dictionary. It is a good idea to always wrap this dictionary with the Quiz class which validates that it is the right format for the application.

# | echo: false
# | output: asis

from helpers import multiple_choice_app, Quiz

questions = Quiz(
    {
        "What ui input is used for plots?": {
            "choices": ["ui.input_plot", "ui.plot_input", "ui.plotInput"],
            "answer": "ui.Input_plot",
        },
        "How do you remove a reacitve link??": {
            "choices": ["reactive.isolate", "req", "reactive.Effect"],
            "answer": "reactive.isolate",
        },
        "What should you use to save an image of a plot to disk?": {
            "choices": ["reactive.Calc", "@ui.output_plot", "reactive.Effect"],
            "answer": "reactive.Effect",
        },
    }
)
