A tick and scars adding up to what is probably a recently imported wild caught ball python.

How's the snake settling in for you otherwise as far as eating and so forth. Personally with these indicators I'd have a fecal float done then if there's indication of internal parasites as well you could take the snake in then for a full going over by the vet. However, if you are unsure or there are any other worrisome issues, get the snake seen (and the fecal done as well of course).
