hashmap in python example

title: understanding hashmap in python: a tutorial with code examples
a hashmap, also known as a dictionary or associative array in some languages, is a data structure that stores key-value pairs. it provides fast retrieval of values based on keys. in python, the built-in dict type serves as a hashmap implementation.
in this tutorial, we'll explore how hashmap works in python, understand its basic operations, and demonstrate its usage with code examples.
let's delve into each of these operations with code examples.
to create a hashmap in python, you can use curly braces {} or the dict() constructor.
to insert a key-value pair into the hashmap and access its value:
to remove a key-value pair from the hashmap:
to update the value associated with a key:
when accessing a key that doesn't exist in the hashmap, a keyerror is raised. you can handle this using exception handling:
in this tutorial, we've covered the basics of hashmap in python, including creation, insertion, access, deletion, and updating operations. understanding hashmaps is essential for efficient data retrieval and manipulation in python programming. experiment with the provided code examples to deepen your understanding of hashmaps and their usage in python.
