In `contextlib`, `_RedirectStream` (the class behind `redirect_stdout` and `redirect_stderr`) returns the current stream target as its context variable, which allows code like this:
``` python
with redirect_stdout(io.StringIO()) as buffer:
do_stuff()
use(buffer.getvalue())
```
where you capture the redirected stream without a separate line to declare the variable.
This isn't documented (See https://docs.python.org/3/library/contextlib.html#contextlib.redirect_stdout), yet is potentially useful.
Unless there's a reason that this isn't documented, I propose that the documentation be modified to include it.
Aside: After initially reporting this against the typeshed (https://github.com/python/typeshed/issues/4283) I'm also working on a PR to the typeshed to include this there. |
