python - 处理除一个异常外的所有异常

Question

如何处理除一个异常之外的所有异常？

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

类似这样，除了不破坏原始回溯:

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

Answer 1

答案是简单地做一个简单的raise:

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

这将重新引发上次抛出的异常，原始堆栈跟踪完好无损(即使它已被处理!)。
