Not really, no. Python/Ruby/Perl interpreters are not “integrated” into the OS like AppleScript and Automator are. They’re just some binaries sitting in /usr/local/bin.

Strictly speaking, yes, but the level of integration is very different. I can get the version of Python which would come bundled elsewhere, but if they remove Automator, there's nothing I can do.

Internet Explorer was integrated into Windows in ways that Calculator or Mine Sweeper weren't — those were merely bundled with the OS.

Python, Perl are the calc.exe of this story — not integrated into the OS, just bundled with it. There's a long history between OSX and Ruby, with MacRuby and RubyCocoa being some efforts to actually integrate Ruby more tightly into the ecosystem, but those efforts have long been abandoned.
