I would like to capture stdout for a portion of a command that doesn’t have a direct python interface.
e.g. SimpleElastix has this command
but I would like to parse the stdout, but I Don’t know how to get at that information.
I tried using something like ’
class Capturing(list): def __enter__(self): self._stdout = sys.stdout sys.stdout = self._stringio = StringIO() return self def __exit__(self, *args): self.extend(self._stringio.getvalue().splitlines()) del self._stringio # free up some memory sys.stdout = self._stdout
but that doesn’t appear to work.
or maybe there is another way around this?
basically I killed some time just to realize I was trying to solve a hard problem that wasn’t necessary for my application… ¯_(ツ)_/¯ 🤷
