Perhaps Palin's modern language (6)
I believe the answer is:
python
I believe this is a double definition.
'perhaps palin's' is the first definition.
(Monty Python member Michael Palin)
'modern language' is the second definition.
(computer programming language)
(Other definitions for python that I've seen before include "Large snake that strangles its prey" , "Big snake that crushes its prey" , "crawler" , "Large tropical snake that crushes its prey" , "Large tropical snake that suffocates its prey" .)
