How do I implement a hash map in Python?

You can implement a hash map in Python using a dictionary. Would you like to see a simple example?

Yes, please show me a basic example.

Here's a basic example:

class HashMap:
    def __init__(self):
        self.size = 10
        self.map = [None] * self.size

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

    def set(self, key, value):
        index = self._hash(key)
        self.map[index] = value

    def get(self, key):
        index = self._hash(key)
        return self.map[index]

This creates a simple hash map with set and get methods.

What are the advantages of using a hash map?

Hash maps provide average O(1) time complexity for lookups, insertions, and deletions, making them very efficient.
