When I create an Object and set its __iter__ method from outside
s = Sequence #one of my own classes
s.__iter__ = new.instancemethod(f,s,Sequence)
I get different results, depending on whether I call
for x in y.__iter__():
for x in y:
The first case does what I expected, i.e. it iterates over whatever f()
yields. In the second case nothing is printed. I have the impression
that it still calls the original __iter__() method (the one defined at
the class level).
Why is that so?
How can I replace the __iter__() method so it does what I want.
The reason I want to do such things is I need to implement operations
similar to what itertools do. However I want my own classes and the
operations are only similar to itertools, but differ in significant
