iterlist 0.4

Treat an iterator as a list

iterlist

Lazily evaluated lists in Python

An iterlist.IterList accepts a single iterable as its only constructor argument.

The iterlist.IterList behaves as a normal list, and will only evaluate the iterable as needed to satisfy requests for element.

If there is a request for index [5], then elements 0 - 5 will be evaluated if they have not been yet. Certain operations like len and negative indexing will force the list to be evaluated. This decision was made to make the iterlist outwardly appear as much like a normal list as possible.

Infinite Iterators

This implementation does not make any attempt to protect you from running out of memory attempting to construct a list from an infinite iterator. A future version may implement InfiniteIterList, which will not have support for any operation which would require consuming the entire iterable.
