Temporarily Redirect stdout/stderr

Question

Is it possible to temporarily redirect stdout/stderr in Python (i.e. for the duration of a method)?

Edit:

The problem with the current solutions (which I at first remembered but then forgot) is that they don't redirect; rather, they just replace the streams in their entirety. Hence, if a method has a local copy of one the variable for any reason (e.g. because the stream was passed as a parameter to something), it won't work.

Any solutions?

Look at contextlib.redirect_stdout(new_target) and contextlib.redirect_stderr(new_target). redirect_stderr is new in Python 3.5.
