what is tuple in python

1# A tuple is a sequence of immutable Python objects. Tuples are
2# sequences, just like lists. The differences between tuples
3# and lists are, the tuples cannot be changed unlike lists and
4# tuples use parentheses, whereas lists use square brackets.

6tup2 = "a", "b", "c", "d";

8# To access values in tuple, use the square brackets for
9# slicing along with the index or indices to obtain value
10# available at that index.
