That is definitely a tick.
Tick removal is nothing fancy... grab it with two fingers and yank it off in a quick motion. They come right out (with no lingering parts remaining). After removing the tick, smash it with something (you'll hear it pop) or drop it in a little vial of rubbing alcohol until it's dead.
Thoroughly check the rest of the snake for other ticks. They can blend well to the untrained eye and can also get under the subcaudal scales and disappear pretty well.
If your snake has ticks there is a 95% chance that it is an import. This suggests that the scars it has are remnants of what it means to be a ball python in the wild.
