Which of the following are not valid operations in python?

 i. Slicing a list

ii. Concatenation of a list and a tuple

 iii. Slicing a dictionary

 iv. Adding an element to an existing tuple

Answer 1

Adding an element to an existing tuple.

Answer 2

Answer : (II) , (III) and (IV)

Reason : 

1. For part (II) - You can't concatenate different data types 

2. For part (III) - Dictionaries and unordered data types so you can't slice them the way you can slice strings or tuples or lists

3. For part (IV) - Whenever you add an element to tuple, A new tuple is formed because Tuples are immutable data types
