[Tutor] how to get str() to use my function?

[Huy Ton That]

You could write __str__ function

>>> class card(object):
...     def __init__(self, card1, card2):
...             self.card1, self.card2 = card1, card2
...     def __str__(self):
...             return str(str(self.card1)+','+str(self.card2))
...
>>> a = card(0,0)
>>> str(a)
'0,0'
