Set vs list vs Dictionary

 DIFFERENCES BETWEEN SET ,LIST AND DICTIONARY

Feature	Set	List	Dictionary
Definition	Unordered collection of unique elements	Ordered collection of elements	Collection of key-value pairs
Syntax	{}	[]	{key1: value1, key2: value2, ...}
Mutable	Yes	Yes	Yes
Ordered	No	Yes	No
Indexing	No	Yes	By keys
Elements	Unique	Duplicates allowed	Keys must be unique, values can be duplicate
Access	Iteration	Indexing, slicing	By key
Example	my_set = {1, 2, 3}	my_list = [1, 2, 3]	my_dict = {'a': 1, 'b': 2}
Use cases	Removing duplicates, checking membership	Sequences, maintaining order	Associative arrays, fast lookup by key

This table highlights the key differences between sets, lists, and dictionaries in terms of their characteristics, syntax, mutability, ordering, indexing, access methods, and common use cases.
