Currently line,

Line 41 in 5df314a

 def __init__(self, a=2, b=[1,1], c=[16,], d=1, e='1', 

reads

def __init__(self, a=2, b=[1,1], c=[16,], d=1, e='1', f=1, g=1, h=1, i=1, j=1, k=1):

These attributes are then set with keyword arguments, they should use the keyword names, rather than the alphabetical placeholders.
