Intuitive information

[annelaura]

I believe it could be intuitive for health (data) researchers if lists and arrays and so on contains some kind of biological information, so that it is easier to understand/imagine what it could be used for.

For example in the Numpy exercise:

now: values = [4, 9, 1, 0, 8, 3, 2, 2, 6, 5, 0]
suggestion: amino_acids = ['A','C','H','L','R',...]

So exercise "Exercise 2: Access items", could be about removing essential amino acids or something like that?
