设置__cause__还会隐式地将__suppress_context__属性设为True,这样使用raise new_exc from None可以有效地将旧异常替换为新异常来显示其目的 (例如将 KeyError 转换为 AttributeError),同时让旧异常在__context__中保持可用状态以便在调试时进行内省。 除了异常本身的回溯以外,默认的回溯还会显示这些串连的异常。_...

-- so it will now trigger a FutureWarning. In your code, you should be explicit: write len(elem) != 0 if you're interested in the number of children, or elem is not None. Fredrik Lundh develops ElementTree and produced the 1.3 version; you can read his article describing 1.3 at ...
在3.7 版更改: Previously DeprecationWarning and FutureWarning were distinguished based on whether a feature was being removed entirely or changing its behaviour. They are now distinguished based on their intended audience and the way they're handled by the default warnings filters.The...
