研究方向
This issue requests that line magics like %timeit return values for easier comparison. The IPython magic system is defined in IPython/core/magics/. A newcomer should examine the current implementation of %timeit in magics/execution.py and understand how magics are registered and executed. The discussion in the issue may reveal design considerations, and the goal is to propose a minimal change that allows return values from magics without breaking existing behavior.
