1) Hash values are integer values assigned to uniquely identify data.
2) In Python hash() function is provided.
3) Using the hash() function you can verify the immutability of a Tuple
4) Set and Dictionary in Python use hashing internally.
5) Hash Collision is possible but is very rare in modern 64 bit architecture.
Hashing involves applying a hashing algorithm to a data item, known as the hashing key, to create a hash value. Hashing algorithms take a large range of values (such as all possible strings or all possible files) and map them onto a smaller set of values (such as a 128 bit number).
Hashing has two main applications. Hashed values can be used to speed data retrieval, and can be used to check the validity of data.
