there are dozillions of "implementation" of python: one
for each release of CPython (2.0, 2.1.2, 2.6.1, 3.x.y...), multiplied for
each OS multiplied for IronPython, Jython, Pypy... etc...

(obviously the
"implementation details" between, say, CPython 2.6.1 and 2.6.2 are really
minor vs Pypy X.Y.Z and IronPython A.B.C)
