Challenge worksheet for sixth form class. Python coding is optional - students doing computer science will find it basic but I felt it was worth introducing the whole class to a practical example of coding. If the code is copied and pasted into the online Jupyter notebook (https://jupyter.org) python editor the exclamation marks will cause an error (easily changed). Students are best writing each line of code into the editor and ensuring the exclamation marks are formatted correctly for python.
