다른 예제는 모두 실행됐는데
max 한번 해보자 해서 해보니 안돼서요..

class Vector(object):
&nbsp; &nbsp; def __init__(self, *args):
&nbsp; &nbsp; &nbsp; &nbsp; '''
&nbsp; &nbsp; &nbsp; &nbsp; Create a Vector, example: v=Vector(5,10)
&nbsp; &nbsp; &nbsp; &nbsp; '''
&nbsp; &nbsp; &nbsp; &nbsp; if(len(args))==0:
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; self._x, self._y=0,0
&nbsp; &nbsp; &nbsp; &nbsp; else:
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; self._x, self._y=args
&nbsp; &nbsp; def __repr__(self):
&nbsp; &nbsp; &nbsp; &nbsp; '''Return the vector informations.'''
&nbsp; &nbsp; &nbsp; &nbsp; return 'Vector(%r, %r)' % (self._x, self._y)
&nbsp; &nbsp; def __add__(self, other):
&nbsp; &nbsp; &nbsp; &nbsp; return Vector(self._x + other._x, self._y + other._y)
&nbsp; &nbsp; def __mul__(self, other):
