Java: why are iterators not copyable
I would think that Iterator.copy() would be quite a handy function. You could implement iterator filters in a much better way.
For example, the only reason in Googles Java Collection for the filter (and similar) functions to use UnmodifiableIterator…

"Pythonic" way to return elements from an iterable as long as a condition based on previous element is true
I am working on some code that needs to constantly take elements from an iterable as long as a condition based on (or related to) the previous element is true. For example, let's say I have a list of numbers:
lst = [0.1, 0.4, 0.2, 0.8, 0.7, 1.1,…

Python filter / max combo - checking for empty iterator
(Using Python 3.1)
I know this question has been asked many times for the general question of testing if iterator is empty; obviously, there's no neat solution to that (I guess for a reason - an iterator doesn't really know if it's empty until it's…

Continue until all iterators are done Python
I cannot use itertools
So the coding seems pretty simple, but I'm having trouble thinking of the algorithm to keep a generator running until all iterations have been processed fully.
