Wheel is a reference to the other Python

Question

PEP 427 describes the move to .whl files from .egg for python packaging purposes.

In the comparisons section of the PEP, there is point 6:

Wheel is a reference to the other Python.

I don't understand this point, what are they trying to say? What other python are they refencing?

Answer 1

.egg is a reference to the snake variety of python, .whl is a reference to Monty Python's "wheel of cheese"
