You will need to get your hands on a thermostat or rheostat. the uth temps get way to hot for ball pythons and will burn them.
So there are about three options, first off a rheostat(dimmer):
If your on a budget this is an option but it needs to be adjusted quite frequently

Second, definitely the best to control would be a proportional thermostat like a Herpstat or Helix, but they can be pricey:

And Lastly, an on/off style thermostat offered in some petco's by zilla that run for 50$ or a Ranco or Johnson for 60-80$:
Helix, Ranco, & Johnson tstats...

and the zilla one...

They will all work, some better and more acurate than others. I currently am using the zilla one and extremely happy with it, but a tstat is a MUST HAVE when dealing with UTHs.
Hope I helped clear up some questions!
Oh, And Welcome to the addiction!
