If you are asking do they need any heating then the answer is yes. Ball pythons need a temperature gradient, 82 cool side - 92 warm side. I prefer to provide belly heat. Some people can get the right temps with a heat lamp alone, but they tend to dry the air so I personally don't care for them. Do you have any other heat source, other than the lamp?

The most likely results of not providing any heat would be refusals to eat and respiratory infections.
