How to Pythonically yield all values from a list?

Question

Suppose I have a list that I wish not to return but to yield values from. What is the most pythonic way to do that?

Here is what I mean. Thanks to some non-lazy comp

Answer 1

Use iter to create a list iterator e.g.

return iter(List)

though if you already have a list, you can just return that, which will be more efficient.
