How do I implement a hash table in Python?

To implement a hash table in Python, you can use a dictionary or create a custom class. Would you like to see both?

Yes, please show me how to create a custom hash table class.

Sure! Here's a simple implementation of a hash table class in Python:

class HashTable:
    def __init__(self):
        self.size = 10
        self.table = [[] for _ in range(self.size)]

    def hash(self, key):
        return hash(key) % self.size

    def insert(self, key, value):
        index = self.hash(key)
        self.table[index].append((key, value))

    def get(self, key):
        index = self.hash(key)
        for k, v in self.table[index]:
            if k == key:
                return v
        return None

What are the advantages of using a hash table?

Hash tables provide efficient data retrieval, with average time complexity of O(1) for insertions and lookups.
