First off, I'd recommend that you read this caresheet. It will prevent a lot of future problems down the road.

Now about your questions... one lamp probably won't be enough. A 6 foot cage for a Ball Python is way overkill and will probably stress out your snake, but I'm sure if you put enough "furniture" in the cage it might be okay. However, I doubt if one lamp would be enough to heat it adequately. You will need to maintain a temperature gradient from the low 80s to the low 90s 24 hours a day. The best way to accomplish that is with an Under Tank Heater (UTH) and a thermostat, although you may need a protected heat lamp if you're going to try and heat a large environment like a 6 foot cage.
