Ok, first of all only temps over 100 could even start to hurt a ball python so calm down. These snakes thrive in high temps.

Your ranges should be: cool side - 82-84 no lower than 78. Warm side - 92-94 no lower than 89. Humidity should stay in the 50's except during sheds when it should go up to the low 70's percent-wise.

For a 10 gallon, especially if you live in cold areas, you can have a UTH on each side for proper temps. They MUST be controlled by thermostats tho. Stats are a must for any snake heating device, but you can get away with a dimmer or rheostat until a thermostat can be obtained.

Here are my recommendations for your tank:
Cover the sides and back with a nice solid background or thick paper, then a layer of cork or foam board insulation, then the blanket if still needed.
If it isn't already, get the UTH on a controlling device and possibly add a second one to the cool side on another device.
Get two identical hides, nice and snug. They're better off when they don't have a 'favorite' hide.
For the lights, use them only for viewing or to raise ambient temps. Best way I've found to do that is to suspend the lamps about 8-12" above the lid.
I can't tell if you've done this, but cover your screen lid with three layers of foil, shiny side down, and cover that/secure it to the lid with a layer of duct or similar tape leaving a 5" square or so opening on the warm side for ventilation.

If those things don't work, then you are probably one of those who should switch over to a tub instead. Tanks can work wonderfully, with a little work, but they don't always do so for everyone. Let us know how things go after some adjustments.
