Documentation?  Real programmers don't read (or write)
documentation. :-)

>>> a = [1,1.0,3.0,3,2.0,2,0,0.0]
>>> a
[1, 1.0, 3.0, 3, 2.0, 2, 0, 0.0]
>>> a.sort()
>>> a
[0, 0.0, 1, 1.0, 2.0, 2, 3.0, 3]

So yes, sort() is stable.

I suppose it's theoretically possible for a different
python implementation to use a different sort algorithm,
but practically speaking, that is very unlikely.
