Someone may have written a with-statement context manager that
abstracts away the swapping.
@contextlib.contextmanager
def swap_stdout(target):
orig_stdout = sys.stdout
sys.stdout = target
try:
yield target
finally:
sys.stdout = orig_stdout
In this case, I can use all kinds of files (open() files, StringIO
objects etc.), and can re-use them if necessary, in order to
prepend/append data.
Closing can happen additionally, if the user wants.
