3.8. Dictionaries#
The last fundamental built-in Python type is the dictionary (dict
). Like lists and tuples, a dictionary contains any number of elements. However, lists and tuples store elements in a sequential way that we address using indexes or slices, whereas dictionaries store elements non-sequentially using keys. This section introduces how to create, read and modify dictionaries.
Tip
If you come from Matlab, Python’s dict
fulfils the same role as Matlab’s struct
.
