Adapt an iterator to behave like a file-like object in Python

Question

I have a generator producing a list of strings. Is there a utility/adapter in Python that could make it look like a file?

For example,

>>> d         


        

Answer 1

There is one called werkzeug.contrib.iterio.IterIO but note that it stores the entire iterator in its memory (up to the point you have read it as a file) so it might not be suitable.
