This appears to be a 2.2.1 bug. Just looking for confirmation or
correction before I put it in the bug tracker:
Python 2.2 (#28, Mar 13 2002, 23:18:18) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> coerce
<built-in function coerce>
>>> class ex(object):
... def __init__(self, v):
... self.v = v
... def __coerce__(self, other):
... return self, ex(other)
... def __add__(self, rhs):
... return ex(self.v + rhs.v)
... def __repr__(self):
... return 'ex(' + repr(self.v) + ')'
...
>>> ex(3)
ex(3)
>>> coerce(ex(1),2.3)
(ex(1), ex(2.2999999999999998))
>>> ex(1).__add__(ex(2))
ex(3)
>>> ex(1)+2.3
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "<stdin>", line 9, in __add__
AttributeError: 'float' object has no attribute 'v'
Thanks,
Dave
