Python - Dictionary & Sets in python programmingComplit Full Notes

Dictionaries and sets are two important data structures in Python programming. Dictionaries: - Dictionaries store key-value pairs and provide efficient lookup based on keys. - Keys must be unique and immutable, while values can be of any data type. - Dictionaries are enclosed in curly braces ({}) and use colons (:) to separate keys and values. - Common operations include adding, accessing, and removing items based on keys. Sets: - Sets store unique elements and support mathematical set operations like union, intersection, and difference. - Sets are enclosed in curly braces ({}) or created using the `set()` function. - Sets are unordered and mutable. - Sets are useful for removing duplicates and checking membership of elements efficiently. Both dictionaries and sets are versatile data structures that are widely used in Python for various applications, including data processing, filtering, and membership checks.
