Python 함수 호출에서 표준 출력을 캡처하는 방법은 무엇입니까?

<code class="python">from io import StringIO
import sys

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</code>

<code class="python">with Capturing() as output:
    do_something(my_object)</code>

<code class="python">with Capturing() as output:
    print('hello world')

print('displays on screen')

with Capturing(output) as output:  # note the constructor argument
    print('hello world2')

print('done')
print('output:', output)</code>

displays on screen
done
output: ['hello world', 'hello world2']
