Well one way to do this (not sure if it is the best way) is something like.
class mypoint:
def __init__(self, *args):
len_args = len(args)
print len_args
if len_args == 0:
self.x = 0
self.y = 0
self.z = 0
elif len_args >=2 and len_args <= 3:
for i in range(len_args):
if args[i] == None: args[i] = 0 #populating the list of
args with defgault values if null(None)
self.x = kargs[0]
self.y = kargs[1]
if len_args == 3: self.z = args[2]
else: raise "Invalid Input"
Now this is not looking for null input such as
p = mypointclass(,,,)
this is an invalid syntax error. Now there must be away to catch for
the blanks but Iam not sure off the top of my head.
hope that helps
