How can I implement a hash map in Python?

You can implement a hash map in Python using a dictionary or by creating a custom class. Would you like to see both methods?

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

Sure! Here's a simple implementation of a hash map using a class:

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 class includes basic methods to set and get values.

What are the limitations of this implementation?

This implementation has a fixed size, which can lead to collisions. It also doesn't handle resizing or more complex data structures.
