常见的想当然

six.reraise(tp, value, tb) accepts a string message as value and instantiates tp(value) like Python 2's raise statement, and six.raise_from(exc, None) retains implicit exception context.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• six.reraise requires value to be an exception instance or None and raises AttributeError when passed a string message, unlike Python 2 raise syntax
• six.reraise with value=None instantiates tp with zero arguments and preserves the provided traceback
• six.reraise raises the provided value instance directly even when tp does not match value's type
• six.raise_from with from_value=None sets __cause__ to None and enables __suppress_context__
• six.raise_from with an exception instance sets __cause__ to the specified cause exception
• six.raise_from instantiates uninstantiated exception classes passed as exc before attaching cause
