What is a Tuple?
Suppose we want to process data about multiple people and for each, we know their
name,
surname,
age,
height,
city, and
county.
We could create 6 lists, one for each piece of information, but as you might have noticed, if we
alter (i.e., modify in some way)
one of the lists,
the indices no longer match,
and the positions can no longer be accessed correctly. What can we do more easily instead? We can use
tuples!
A
tuple is also a kind of list, but its
elements are ordered and
immutable, and they are
defined using round brackets:
DETAILS
Above, we defined two tuples, in our case for
Fox and
Dana from the
X files series, let's say:
Each element of the tuples stores a specific piece of information that we have appropriately entered,
so as to obtain a coherent data structure.
We know that the created tuples store the
age at index
2, and the
county at
5, etc. Thus,
we have a consistent mechanism for any other person, and we will create a tuple for each one.
Note: For those who have studied C++, tuples are
similar to the
struct type.
We cannot add, delete, or modify elements defined in a tuple! Any such operation will give us a runtime error:
But what can we do instead?
