The cheatsheet is a Jupyter Notebook file with the .ipynb extension. The cheatsheet is a collection of code snippets and explanations.
The cheatsheet is divided into sections and sub-sections. Each section contains a collection of related code snippets. The sections are organized in a way that the most frequently used code snippets are at the top.
These are my solutions to some of the past exams.
Warning: the solutions and the cheatsheet are provided as they are, there is no guarantee of correctness. Any proposal for correction is welcome
