# sequences, just like lists. The differences between tuples
# and lists are, the tuples cannot be changed unlike lists and
# tuples use parentheses, whereas lists use square brackets.
tup1 = ('physics', 'chemistry', 1997, 2000);
tup2 = "a", "b", "c", "d";

# To access values in tuple, use the square brackets for
# slicing along with the index or indices to obtain value
# available at that index.
tup1[0] # Output: 'physics'

tup1 = (12, 34.56);
tup2 = ('abc', 'xyz');

# Following action is not valid for tuples

# So let's create a new tuple as follows
tup3 = tup1 + tup2;
print tup3;
