Tuples are immutable python sequences, i.e. you cannot change elements of a tuple in place. Tuples’ items are indexed. Tuples store a reference at each index. Tuples can be indexed sliced and its individual items can be indexed, len (T) returns count of tuple elements. Tuple manipulations functions are: len (), max (), min () and tuple ().
(i) What is the type of Tuple in Python?
(ii) Which method is used to return count of tuple elements?
(iii) What are the functions of Tuple?
(iv) Which type of brackets is used to define the tuple?
(v) Which one is immutable Python sequence?
