Python got a reputation for being good for quick prototyping.

Python had an easy to use CLI and supportive docs that made it easy to throw things together.

Case-in-point, the language literally includes functions like:

  dir

That facilitate treating library objects as simple directories of functionality.

Default arithmetic library supports APA.

There's just a lot of stuff that's frictionless in Python, where Ruby has sprawling and unintuitive syntax, and mandatory programming constructs.
