As with leopard geckos, many different colors/patterns have been bred by generations of selective breeding. They are both definitely Burmese pythons because the only other python that is commonly albino is the ball python, which they are both not.
Bob Clark and Co. have also produced various hypomelanistic/"albino" specimens of other python species, including Retics... Let's say that the whole exterieur (including pattern, shape of the body/head, size...) of the snake indicates without doubt that this is one of the many, many "Albino" Python molurus in the pet trade, of which most are of the bivittatus subspecies. Better?
The Burmese python, both the "normal" and the "albino" aka amelanistic morph, is probably the most common big snake species in the international pet trade. Back in the 1980s, the first amelanistic Burmese pythons were sold for thousands of dollars. Nowadays, the morph is commonplace in the pet trade and much, much cheaper. Due to this lower price, greedy, ignorant salesmen, stupid, irresponsible private owners and its large size, it is also one of the more common reptiles in both veterinary clinics and animal shelters...
