Python basics
=============

Welcome to Python Basics! I have written this book to provide an easy and
practical introduction to Python. The book is not intended to be a comprehensive
reference guide to Python, but rather the goal is to give you a basic
familiarity with Python and enable you to quickly write your own programs.

The book is published under the `BSD-3-Clause license
<https://github.com/veit/python-basics-tutorial-de?tab=BSD-3-Clause-1-ov-file#readme>`_,
so you may adapt and publish the book for your own purposes, provided you
retain the licence and copyright notice.

I would like to thank `cusy GmbH <https://cusy.io/en/front-page>`_ for
generously allowing me to spend my time writing this book. In addition, I would
like to thank Kristian Rother not only for the support and advice he has given
me over the years on this book, but also for the editing that has made this book
better. I would also like to thank Steffen Dahlem for the idea and realisation
of a more sustainable book production. Finally, my heartfelt thanks also go to
the reviewers, whose insights and feedback were a great help.

.. note::
   If you have suggestions for improvements, I would be happy to :doc:`receive
   <contribute>` them.

Python basics is part of a series of tutorials on data analysis and
visualisation:

* :doc:`jupyter-tutorial:index`
* `Python für Data Science <https://www.python4data.science/en/latest/>`_
* `PyViz-Tutorial <https://pyviz-tutorial.readthedocs.io/de/latest/>`_
* `cusy Design-System: Datenvisualisierung
  <https://www.cusy.design/de/latest/viz/index.html>`_

All tutorials serve as seminar documents for our harmonised training courses:
