Python Programming

If you do not need a full class, you can sometimes create a simple data structure with attributes using namedtuple.

Remember the coordinates in your robot project when you had to use coord[0] and coord[1] to represent the row and col respectively? You can actually use namedtuples to make your tuples more self-explanatory by naming coord[0] as coord.row and coord[1] and coord.col! You can even make your tuple a type (say Coordinates!)

Hopefully the example below is self-explanatory!

>>> from collections import namedtuple
>>> Coordinates = namedtuple("Coordinates", "row col")
>>> print(type(Coordinates))
<class 'type'>
>>> position = Coordinates(4, 5)
>>> print(position)
Coordinates(row=4, col=5)
>>> print(position.row)
4
>>> print(position.col)
5
>>> print(position[0])  # This still works too!
4
>>> print(position[1])
5
>>> Coordinates(4, 5) == (4, 5)  # Coordinates is still a tuple!
True
