The tutorial will be hands on. I will start with a blank Notebook for each topic and develop the content step-by-step. The participants are encouraged to type along. My typing speed is usually appropriate and allows participants to follow. The students will receive a comprehensive PDF with all course content as well Python source code files for all use cases and large code blocks I use. I will load these files in my Notebook. The students can do the same or open the files in their preferred editor or IDE.

I also explicitly ask for feedback if I am too fast or things are unclear. I encourage questions at any time. In fact, questions and my answers are often an important part of my teaching, making the learning experience much more lively and typically more useful.

So the participants will be active throughout the whole tutorial. There will be two exercises that each participant has to do on its own (or in breakout rooms if the tutorials should be remote) during the tutorial. We will look at the solutions during the tutorial. I also supply a solutions PDF after the tutorial.
