 The TeachOpenCADD platform is not a Python programming course from scratch but teaches how to solve tasks in cheminformatics and structural bioinformatics programmatically.
 If you wish to get started first with a Python programming introduction before diving into the TeachOpenCADD material, here are a few great resources to do so:
 
-- `AI in Medicine course <https://github.com/volkamerlab/ai_in_medicine>`_ by the `Volkamer Lab <https://volkamerlab.org/>`_ and `Ritter Lab <https://psychiatrie-psychotherapie.charite.de/metas/person/person/address_detail/ritter-7/>`_ at the Charité: Introduction to Python basics, Jupyter Notebook, and important data science packages such as ``pandas``, ``matplotlib``, and ``scikit-learn``
-- `Python for Chemists course <https://github.com/GDChCICTeam/python-for-chemists>`_ by the `GDCh/CIC <https://en.gdch.de/network-structures/divisions/computers-in-chemistry-cic.html>`_ team: Crash-course introduction to Python for natural scientists
