“So, a ‘dictionary’ has (key, value) pairs apparently.
What are these things? You can think of dictionaries as a
generalisation of lists. In our earlier examples we got the
contents of the lists by a number.

you’ve forgotten it was in this tute). In that case the number 0
was the ‘key’, and the text of the question was the
‘value’.”
