处理除一个例外的所有例外

Question

如何处理除一个例外以外的所有例外

try:
    something
except <any Exception except for a NoChildException>:
    # handling

像这样的东西,除了不破坏原始追溯:

try:
    something
except NoChildException:
    raise NoChildException
except Exception:
    # handling

Answer 1

答案是简单地做一个raise:

try:
    ...
except NoChildException:
    # optionally, do some stuff here and then ...
    raise
except Exception:
    # handling

这将重新引发最后抛出的异常,原始堆栈跟踪保持不变(即使它已被处理!).
