Python is a term used to refer to one of the main collaborators on the BBC sketch show Monty Python's Flying Circus.
The original pythons were Terry Gilliam, Terry Jones, John Cleese, Eric Idle, Graham Chapman and Michael Palin.
Often used in the context of "the n surviving Pythons", since one of them is dead and the rest will inevitably follow. When n=0, we will have lost the last of a unique group of comedians who changed the face of British comedy.
Python can also be used as an abbreviated form of the name Monty Python's Flying Circus
