Referring to elements. Nested Tuples
Tuples can contain other tuples as elements. Also, lists, strings, etc. can be used as elements of a tuple.
Accessing elements is similar to accessing elements of a list, specifying the index of the element in square brackets. Indexing starts from zero.
When referring to nested elements, additional square brackets must be used.
my_tuple = (('a', 'b', 'c'), [1, 2], ((1, 'a' ), ('b', 'c')))
print(my_tuple[2][1]) # ('b', 'c')
