The Python is an easy way of doing water changes & gravel vacs, if you don't mind wasting some water. I already go through enough water as it is, any way of saving it is a good thing.
If you have a small pond pump, or large powerhead you can use this to get the siphon started. I do this with large tubs in the basement, it's easier than going all the way to the other end of the basement to suck on the end of a garden hose that has been stuck in the sump pump pit for years.
