After a quick Google search, I found this...

The Artis Zoo in Amsterdam contains three adult female Burmese pythons but no males. One female was born in 1993 and has been separated from males since 1995. She has produced a single clutch every spring starting in 1997 up to 2002. Healthy embryos have been observed in 25-30% of the eggs every year. No material of the 1997-2000 clutches had been saved for later use in a genetic study. Seven embryos were isolated from eggs of the 2001 clutch after a 24 day incubation period. The results of this test showed that six out of seven microsatellite loci were monomorphic and all individuals were homozygous for the same allele. All seven young had identical fingerprints, and all the markers of the offspring were also found in their mother. So the young are genetically identical to their mother and do not show markers that suggest the involvement of a father. These observations then suggest that this female python is parthenogenetic.
