Hi,
I am getting an error while executing the following snippet. If i comment out
method __repr__ , it works fine.
class fs(frozenset):
def __new__(cls, *data):
data = sorted(data)
self = frozenset.__new__(cls, data)
self.__data = data
return self
def __repr__(self):
return "%s(%r)" % (self.__class__.__name__, self.__data)
a1 = fs(1,2,3)
a2 = fs(3,4,5)
print a1.difference(a2)
Error:
return "%s(%r)" % (self.__class__.__name__, self.__data)
AttributeError: 'fs' object has no attribute '_fs__data'
Please help me in fixing this.
When posting problems like this, please include the Python version.
If you ran this with 2.6, please run the following:
x = frozenset('abc')
y = frozenset('bcd')
z = x.difference(y)
print(id(x) != id(z))
This should print (True), but if 2.6 has a bug for frozenset similar one
it has for bytearrays, it will print (False) and that would explain your
error.
