Python is simple to read / write and easier to reason about, especially for people that need a programming language to solve a problem but are not software engineers.

The reason it won, especially in data analysis, is because most data analyst are/were not software engineer and Python feels more natural to people.

The indentation is not a big problem when a decent text editor is used
