Air Quality - Pollutant Index - India

This mini project shows the Air Quality Index (Industrial Air Pollution) from various locations in India in a Tableau Public dashboard.
The data is sourced from data.gov.in API using Python for cleaning & loading the data in Google Sheets.
Data is updated daily (or manually) using GitHub Actions or AWS Lambda.

My Workflow

GitHub Action "run-python.yml"

• Google credentials are stored in GitHub Actions Environment Secrets.
• data.gov.in API Key is also stored in GitHub Actions Environment Secrets.
• A GitHub Action is created that can run manually or on a schedule [12PM UTC (8PM SGT)].
• Python 3.9 is setup using actions/setup-python@v2.3.0 and the pip packages are cached.
• Dependencies are installed using py-actions/py-dependency-install@v2 based on requirements.txt (google auth, pygsheets & pandas).
• The Environment Secrets are exported to environment variables.
• Finally, the Python script is run with the environment variables passed as parameters.

Wacky Wildcards

• I tried to use this workflow as a replacement / complement to the AWS Lambda function that processes the Python script at 8AM SGT.

Python script "Air Quality Index India.py"

• The script connects to data.gov.in API using API Key passed as a parameter.
• Then it pulls the latest AQI data for India and stores in pandas dataframe.
• The data is cleaned, formatted and the columns are renamed. Nulls are replaced by 0.
• Google sheet is…
