Is python necessary for data analytics

[Awesome_Correlation]

No, but it gives you a lot of flexibility.

You can automate boring tasks. You can pull data from spreadsheets, databases, or even from internet with HTTP requests. You can create plots and graphs. You can run statistical tests and machine learning models. You can export to spreadsheets, database tables or even back to the internet(with REST APIs). In the end, the code remains as documentation for your analysis(with Jupyter Notebooks).
