Baca, it may be wise to get her and the eggs into a box. I'm guessing she doesnt have a hiding box else she would have laid the eggs in that.
Whats substrate is she on? Is that sand?
If i was you i would either get her off the eggs myself or wait for her to leave them to bask. When this happens i would quickly lift the eggs(making sure my fingers go right under the egg mass to avoid any dropping off from underneath) and place them in a large open-topped or hinge lidded box with a thick dry substrate(i prefer grass cuttings). She should return to them without a problem. If open-topped, this box needs to be heavy so it doesnt flip up when she climbs over the side edge when leaving/returning. . Keep the box down the cool end so there's no chances of overheating them. She will decide whether or not she wants to bask occasionally.
In doing this there is a good chance that eggs will hatch successfully. If you leave her where she is in that photo the eggs may dry out and die through lack of humidity and a sandy substrate may actually suck moisture out of the eggs. I also dont like that she laid them directly under the globe. They need to be somewhere cool and have the female working to keep them warm. Is there an enclosure underneath hers? The globe from the underneath enclosure may make the floor to her enclosure too warm, which will affect the eggs also.
Dont worry about feeding her. She can go well into next year without a feed.
As for the babies, you will have plenty of warning that they hatching. Their heads will stick out of the eggs for a day before emerging completely. Dont force them out at this time else they will probably die. They are still absorbing yolk. After a day with their heads out they will come out completely and probably head for the nearest safe place. If the cage is bare then the nearest safe place will be under the mother or in her coils. They will be snappy and there's a good chance the mother will be too. You may need to throw a towel over her while removing the babies.
I envy you mate!! I'd love a clutch of Water Python eggs right now!! Nice snakes indeed.
