Hash table and Python dictionary

One of the most useful Python collections are the dictionary, which is a associative data type where you can store Key-dat A pairs. It is implemented using hash tables.

Hash Table is a collection of items which be stored in such a by-make it easy to find item. Each position of the hash table, often called a slots, can hold an item and are named by an integer value starting At 0. The mapping between an item and the slot where this item belongs in the hash table is called the hash function. A perfect hash function maps every items into a unique slot. When both items hash to the same slot, collision happens. and a systematic method, which called collision resolution, for placing the second item in the hash table must be put FORW Ard.
