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.

Visualization in Python - Case Study: Urban Accidents in India

I was reading a news item related to accidents and wanted to explore more. With a bit of search, I landed in Govt of India Data website. The website had so much data and visualization in different industries/areas. With another double down, I managed to download the data for Urban accidents in all Indian states.

With a couple of hours of staring at the data and coding, managed to pull out the following charts. The data had absolute numbers for each state and I had come up with a ranking on the following KPIs (had to download population data from Wikipedia according to 2011 census report)

1. Number of urban accidents
2. Percentage of accidents with a weighted urban population

Feedback loop: Data -> Information -> Insights -> Business Transformation

Tools Used:

1. Python (no Numpy or anything else)
2. Matplotlib for visualization
3. Jupyter to cook Python code quickly

Source code and visualization can be found in my github repo

Questions:

1. Why GA has more accidents than TN? (why??)
2. Why HP has more accidents than PY? (terrain?)
3. What can be done to minimize accidents?
