Question:

Which of the following data structures in Python is immutable?

Options:

        
• A) List
        
• B) Dictionary
        
• C) Tuple
        
• D) Set
    

Correct Answer: C) Tuple

Explanation:

In Python, data types are classified as either mutable (can be altered after creation) or immutable (cannot be changed after creation).

        
• Tuple (Option C - Correct): Tuples are defined using parentheses (). Once a tuple is defined, its elements cannot be reassigned, appended, or removed.
        
• List (Option A - Incorrect): Lists are mutable sequences. You can freely change elements, append new items, or delete elements.
        
• Dictionary (Option B - Incorrect): Dictionaries are mutable associative arrays consisting of key-value pairs that can be modified dynamically.
        
• Set (Option D - Incorrect): Sets are mutable collections of unique, unordered elements. You can add or remove items from a set.
    

Key Concept: Common immutable data types in Python include int, float, str, tuple, and frozenset.
