Named tuples

So, what do we do when we want to group values together, but know we're frequently going to need to access them individually? There are actually several options. We could use an empty object, as discussed previously (but that is rarely useful, unless we anticipate adding behavior later), or we could use a dictionary (most useful if we don't know exactly how much data or which specific data will be stored), as we'll cover in a later section. Two other options are named tuples, which we'll discuss here, and dataclasses, in the next section.

If we do not need to add behavior to the object, and we know in advance which attributes we need to store, we can use a named tuple. Named tuples are tuples with attitude. They are a great way ...
