The obvious simple near-equivalent is:
data = range(33,99)
print data.ind

If you're doing a lot of this kind of thing, you probably want to use
numpy::
>>> import numpy
>>> x = numpy.array([0, 1
a =
[0,1,2,3,4,2,8,9]

You can try this:
print filter( lambda x: a[x]==2, range(len(a)))
However it's not the best solution...

Python gives very elastic syntax, you can simply do:
data = [0,1,2,3,4,2,8,9]
print [pos for pos, el in enumerate(data) if el==2]
