1) Tuple is exactly same as List except that it is immutable. i.e once we creates Tuple

object, we cannot perform any changes in that object.

2) Hence Tuple is Read only version of List.

3) If our data is fixed and never changes then we should go for Tuple.

4) Insertion Order is preserved

5) Duplicates are allowed

6) Heterogeneous objects are allowed.

7) We can preserve insertion order and we can differentiate duplicate objects by using

index. Hence index will play very important role in Tuple also.

8) Tuple support both +ve and -ve index. +ve index means forward direction (from left to

right) and -ve index means backward direction (from right to left)

9) We can represent Tuple elements within Parenthesis and with comma seperator.

10) Parenethesis are optional but recommended to use.
