It also depends on how much you can afford to spend on said python - Womas certainly are lovely snakes - but not every first-time keeper can fork out the $700 + on one snake.
I agree with the above comments that Murray Darlings are beautiful snakes with an exceptionally docile temperment, great feeding response and an agreeable price tag to match - however 3ftx2ftx2ft isn't really big enough for an adult, and if this is all the space you have you would have to stick to an antaresia (Children's, Maccie or Stimson).
Also keep in mind that although it might seem pretty amazing to get an enormous snake (such as an olive or a scrubby) - you also have to pay for enormous meals, an enormous enclosure and possibly - if that snake turns on you - an enormous hospital bill. Best to think things through...
That said, don't go for second best - if you don't REALLY want a
childrens python - don't get one just because it's "Suitable" - you'll probably regret it and end up buying the one you originally wanted anyway - just think about all the factors as outlined by the very experienced herpers above.
