Patch built-in python objects
Forbiddenfruit by clarete
This question already has an answer here:
I know, this is wrong, but is it possible?
I thought an object is considered an iterable when its .__iter__ method returned an iterator? So why doesn't this work?
>>> from forbiddenfruit import curse
>>> def __iter__(self):
... for i in range(self):
... yield i
>>> curse(int, "__iter__", __iter__)
>>> for x in 5:
... print x
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
int does seem to have an __iter__ method now:
>>> int(5).__iter__
<bound method int.__iter__ of 5>
