A Quick Overview of Hash Tables

Explore the fundamentals of hash tables, including their constant time complexity operations and implementation strategies in Python. Understand how hash functions impact performance and memory usage to effectively use this data structure.

We'll cover the following...

Complete Implementation

In the previous lessons, we discussed each aspect of a hash table in detail. Below, you can find the complete hash table class.

Python 3.5
from HashTable import HashTable
table = HashTable()  # Create a HashTable
print(table.is_empty())
table.insert("This", 1)
table.insert("is", 2)
table.insert("a", 3)
table.insert("Test", 4)
table.insert("Driver", 5)
print("Table Size: " + str(table.get_size()))
print("The value for 'is' key: " + str(table.search("is")))
table.delete("is")
table.delete("a")
print("Table Size: " + str(table.get_size()))
