Guido disallowed returning a len method on iterators. He expected
bool(it) to be False.
The recipes section of the itertools docs has code for
combinations_with_replacement(). It was not included originally because
it was unclear whether there was actually a need to generate them.
Possibly, people are mainly interested in knowing how many there are but
having no need to actually enumerate them. That being said, if I get
more requests or if some real world use cases arise, I would be happy to
C the recipe and add it in Py2.7. |
