Programmierung in Python

Auf dieser Seite finden Sie die Quellen zur Veranstaltung "Programmierung in Python" von Prof. Dr. Martin Hepp an der Universität der Bundeswehr München.

Der Kurs ist über https://mfhepp.github.io/pip/ zugänglich.

Diese Seite ist nur für Entwickler oder Personen gedacht, die den Kurs lokal installieren oder verändern möchten.

Overview

Dependencies and Installation

The materials are intended to be run from Jupyter Notebooks within the Anaconda package.

You need the following components

• RISE (https://rise.readthedocs.io/en/maint-5.5/)

$ conda install -c conda-forge rise

• NBextensions with Table of Contents (2), Split Columns, RISE installed an enabled

$ conda install -c conda-forge jupyter_contrib_nbextensions

• decktape for creating PDFs (https://github.com/astefanutti/decktape)

If you do not have npm, install that first with Homebrew:

$ brew install node # install npm

Then install decktape

$ npm install -g decktape
$ decktape

Usage

First make sure that the Table of Contents (2), Split Columns and RISE checkboxes are activated in the NBextensions pane. In Jupyter Notebooks, go to

Edit -> nbextensions config

Presentation Mode

In order to present the slides, simply click on the RISE icon (tiny barchart) in Jupyter Notebooks. Set your browser to full-screen mode.

Hint: The exact rendering depends on the resolution of your screen, so if you are presenting using different projectors or computers, the layout may change. I am still searching for a solution for this.

Generate PDFs

First, you need to fetch the session ID for you running Jupyer Notebooks process. This can be found in the terminal window in which it is running. Find this section:

    To access the notebook, open this file in a browser:
        file:///Users/...
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=6dfjsdja3c75f6bc21d5c2a7891774b3fc540ca2615765eb6c5

Then, generate a PDF using

$ decktape rise <URI_of_your_presentation>?token=<token_from above> <filename.pdf>

Note: Unfortunately, the slides numbers are not included in the PDFs.

RISE Meta-data

I currently use the following settings for rise and tocin the notebook's meta-data:

"rise": {
    "backimage": "background.png",
    "center": false,
    "enable_chalkboard": false,
    "footer": "Univ.-Prof. Dr. Martin Hepp, martin.hepp@unibw.de",
    "header": "Programmierung in Python",
    "showSlideNumber": "pdf",
    "slideNumber": "c/t",
    "theme": "chesterish",
    "transition": "none"
  },
  "toc": {
    "nav_menu": {},
    "number_sections": true,
    "sideBar": true,
    "skip_h1_title": false,
    "base_numbering": 1,
    "title_cell": "Table of Contents",
    "title_sidebar": "Inhaltsverzeichnis",
    "toc_cell": false,
    "toc_position": {
      "height": "calc(100% - 180px)",
      "left": "10px",
      "top": "150px",
      "width": "543.391px"
    },
    "toc_section_display": true,
    "toc_window_display": false
  }

Open Issues

• The slide numbers do not show in the PDF version of the slides.
• I am still looking for a way to generate HTML-only versions of the presentations that preserve the reveal.js features. The standard output with jupyter-nbconvert or the respective menu option in Jupyter notebook is incomplete and breaks over some markup for reveal.js.
• I would like to include the date of creation as a version signature to the footer of PDF versions, but I have not yet figured out how. Using an f-String as the value for the "rise: {"header": ...} value might work, but where will I put the datetime import?
• Need a way to generate an HTML version of the notebook that includes the numbering from the ToC extension, but not the ToC (or the ToC in the first cell).
• I would like to have the headline numbering for subsequent notebooks start at 2, 3, 4 ... respectively - is there a way to set this?
• When generating PDFs with decktape, there are a few errors regarding missing includes / 404s; what is the effect and how to solve this?
• I would like to have all fragments of a slide appear on a single PDF page, but RISE/decktape do not seem to pass the respective URI parameter.
• I need a mechanism to hide solutions from the tutorial in at least an HTML or PDF version, ideally managed via a generic tag or cell meta-data. The two available extensions work only in the ipynb view, neither in HTML export nor PDF.
• The font size varies with output resolution. This is a nuissance.

This course and my entire workflow for development-centric presentation materials is based on the great RISE extension by @damianavila, and DeckTape by @astefanutti. Thanks!
