Does "with ... as ...:" work with non-files?

Question

For example, this code doesn't work:
with int("5") as a:
print(a)

Answer 1

Actually it works with objects, where those objects provide __enter__ and __exit__ methods.

If you defined your own integer object with those methods, you could also 'with' them.
