I gotta second that motion ...

There are lots of great language interpreters out there.   Python is one; Perl is another.   (During the course of any given work-week, I often use both of these and several more, switching between them without pause.)   It is, in fact, very common to find more than one such tool being used in a project at the same time ... and never the twain shall meet.   Simply use each language for its own particular advantages (or, as the case may be, “because it is (already) there,” and ... don’t borrow trouble.   You do not have a problem now.   Do not make one for yourself.   The present situation is quite defensible and serviceable.   It needs neither remedy nor improvement.
