Question: Which of the following data types in Python is immutable?

Options:

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

Correct Answer: C) Tuple

Explanation:

In Python, an object is considered immutable if its value or state cannot be changed once it is created. Conversely, a mutable object can be altered after instantiation.

    
• Tuple (Option C - Correct): Tuples are sequences that are immutable. Once created, elements cannot be added, removed, or updated in place. Attempting to modify an element will result in a TypeError.
    
• List (Option A - Incorrect): Lists are mutable ordered sequences. Elements can be added using methods like append(), modified by index assignment, or removed using pop().
    
• Dictionary (Option B - Incorrect): Dictionaries are mutable mappings of keys to values. Keys and values can be inserted, updated, or deleted at runtime.
    
• Set (Option D - Incorrect): Sets are mutable collections of unique elements. Elements can be added using add() or removed using remove().

Key Takeaway: Standard immutable types in Python include int, float, bool, str, tuple, and frozenset.
