I dump the bucket on my lawn. If I were using a python, I would have to run the hose outside, and leave a door or window open, and hook it up to the garden hose, make sure the valve at the tank is shut, run outside and start the water, run back in and open the valve, vac, shut the valve, run outside and stop the water, run in and open the valve and take the end out of the tank, run out and turn on the water to suck the hose out, turn off the water, disconnect the python, and roll it up and put it away... Bigger pain than the bucket. Besides, most of the time my waterchanges are small enough that it wouldn't be worth hooking up a python anyway, even if I were using a sink right next to the tank.
