And it's easy enough if you don't care about them being different.. def __repr__(self): return str(self)If I ever wanted __str__ and __repr__ to return the same thing, I would make them equal:def __str__(self): return 'whatever you want' __repr__ = __str__That makes it more obvious to me what's going on. As a bonus, it saves one method call for every repr call.
It's even easier to define only __repr__, __str__ defaults to it:
class OnlyRepr(object):
... def __repr__(self): return "repr called" ...
class OnlyStr(object):
... def __str__(self): return "str called" ...
class Both(OnlyRepr, OnlyStr):
... pass ...
r = OnlyRepr() s = OnlyStr() b = Both() print "only repr:", repr(r), str(r)
only repr: repr called repr called
print "only str: ", repr(s), str(s)
only str: <__main__.OnlyStr object at 0x00BA10F0> str called
print "both: ", repr(b), str(b)
both: repr called str called -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
