Urgent help for Data Science Training needed

Description

As part of an online training provided by my employer I need to finish a Data Science project.
The idea of the project is that from the provided data, the data set will be read, cleaned and processed. After that machine learning models need to be trained, evaluated and used for the prediction of future developments.
All the code has to be written in Python.
The entire project is within a .ipynb notebook. There the project is divided into smaller tasks. The main problem here is that the notebook and the tasks are written in German.
The code should be commented so I get a understanding of it. Comments and code, of course, can be in English.
