Here is my presentation/slide deck with all the code I would expect students to know.
Python Code To Know GCSE and A Level (1)

You can access the Python notebook for these examples here: https://colab.research.google.com/gist/laura-james/b6dfbc164be9c189d7c1cd86b22437a2/python_code_to_know-2.ipynb

There is also an Python notebook which hopefully explains OOP principles for A Level you can find here:
