本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

案例
HOW- 目标
- Require instantiated exception instances rather than string messages in six.reraise, and suppress context chaining when from_value is None in six.raise_from
- 符号
-
- six.reraise
- six.raise_from
- 环境
- python

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
