Building a Hash Table from Scratch

Learn about how hash tables are implemented in Python.

Hash Table Using Bucket Chaining #

As said earlier, hash tables are implemented using lists in Python. The implementation itself is quite simple. We will use the chaining strategy along with the resize operation to avoid collisions in the table.

All the elements with the same hash key will be stored in a linked list at that index. In data structures, these lists are called buckets. The size of the hash table is set as n*m where n is the number of keys it can hold and m is the number of slots each bucket contains. Each slot holds a key/value pair.
