Reading the code one clearly sees why Python is so well suited for these kinds of applications, one-shot script executables: Really nice string ops, regex, file io etc. One of my favorite languages. The other is C# for everything else, that Python is not that suitable for: Huge complex codebases, type safeness, more strict performance requirements etc. Specially the static typing. The dynamism and lack of type annotations of Python really bothered me when I was developing a somewhat complex desktop app in it some years ago. I guess I'm a static typing guy with optional dynamism kinda person.
If you haven't checked back lately, type annotations in Python are getting better and better. Built-in support via the typing module and a strong community package in mypy.
