Please help me to convert a function from vb to python

[buran]

if you call it like this

calc ('11010003000C')

your function returns '3601'

One of the packages I testes - PyCRC calculates it as 3191

>>> from PyCRC.CRC16 import CRC16
>>> print CRC16().calculate('11010003000C')
3191
>>>

both not what you expect
