In reality, hash functions are much more complex, but for simplicity, let's use a hash function that maps each name to an index by taking the ASCII value of the first letter of the name modulo the size of the table: defsimple_hash(key, array_size):returnord(key[0]) % array_size ...
maps = [] for i in range(n): self.maps.append(LinearMap()) def find_map(self, k): index = hash(k) % len(self.maps) return self.maps[index] def add(self, k, v): m = self.find_map(k) m.add(k, v) def get(self, k): m = self.find_map(k) return m.get(k) class...

For example, a multimap lets you have more than one value per key, while a bidirectional map not only maps keys to values but also provides mapping in the opposite direction. However, in this tutorial, you’re only going to consider the regular dictionary, which maps exactly one value to ...
