My bad, I haven't seriously used Python for over 15 years now, so I stand corrected (and will clarify the post).

My main point stands though, Python strings have an internal representation, but it's not exposed to the user like Ruby strings.

Same. Thank you for the correction, I'll update the post.

Cool, although I feel if on one side you have Java, JavaScript, Python, Go and on the other Perl, PHP, C/C++, Ruby, Rust it's hard to say overwhelming majority in either direction.

Also someone below claims python byte arrays can be considered mutable strings, although I have no idea of the stringy ergonomics of that and whether it would be convenient to do - I try to avoid python too.
