Hashmap:
A hashmap is also known as a hash table. A hashmap is one of the data structures in python that maps keys to its value pairs. It is somewhat similar to a dictionary since dictionaries also store key-value pairs but hashmaps use a function to compute the index value that stores or holds the elements to be searched. This function or hashing() helps to retrieve mapped elements in a faster manner than the normal sequential or linear search. Simply we can say that hash tables store key-value pairs and the key is generated using a hash function. In python, we use the built-in dictionary data structures to implement hash maps. The elements of a hashmap are not ordered and can be changed.
