before anybody say's anything, i screwed up when i pasted the code,
here is what i really have...
def method(self, other):
if isinstance(other, Point2d):
x, y = other.x, other.y
else:
x, y = other[0], other[1]
return self.x+x, self.y+y
#and the fixed class :)
class Point2d():
def __init__(self, x, y=None):
if type(x) == tuple:
self.x = x[0]
self.y = x[1]
else:
self.x = x
self.y = y
def __str__(self):
return 'Point2d(%f, %f)' %(self.x, self.y)
def __add__(self, other):
if isinstance(other, Point2d):
x, y = other.x, other.y
else:
x, y = other[0], other[1]
return (self.x+x, self.y+y)
def __sub__(self, other):
pass
def __iadd__(self, other): #+=
pass
def __isub__(self, other): #-=
pass
PS: i know i could have one method like
def get_xy(self, other):
#conditional
and then call it like
x, y = self.get_xy(other)
but that seems pretty clumsy. There must be a more Pythonic way!
