Hashmaps - Python

It has been a while that I wrote some code. Been learning Python using Udemy for some time. Python is truly expressive and batteries included language. I read about Hashmaps and thought I should give it a try. Within a very short duration (say 1 hour), I was kind of able to complete full hashmap implementation along with basic tests using PyTest.
