+
+Python has rapidly advanced to the most popular programming language in science and
+research. From data analysis to simulation and preparation of publications, all can be done in
+Python with appropriate libraries and implementing own modules. We will discuss Python
+Enhancement Proposals (PEP) and how these can help you write cleaner code. Common
+pitfalls in Python will be explained with examples. We will demonstrate typical “bad
+programming” and how to code the examples in a more pythonic way.
+
+## Prerequisites
+Basic Python knowledge is required. Participants need a laptop/PC with camera and
+microphone.
+
+## Learning objectives
+After the course participants will be able to
+- Understand the basic PEP recommendations
+- Use a linter and code formatter to ensure following of the guidelines
+- Write better=more readable code
+- Avoid bugs through best practices for example in passing keyword arguments
+
+# Time and place
