本文介绍了关于捕获任何异常的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我该如何写一个 try / except 阻止所有异常的块？
How can I write a try/except block that catches all exceptions?
推荐答案
您可以，但您可能不应该这样做：
You can but you probably shouldn't:
try:
do_something()
except:
print "Caught it!"
但是，这也会捕获诸如 KeyboardInterrupt 并且您通常不想要那个，对吗？除非您立即重新引发异常-参见以下示例来自文档：
However, this will also catch exceptions like KeyboardInterrupt and you usually don't want that, do you? Unless you re-raise the exception right away - see the following example from the docs:
try:
f = open('myfile.txt')
s = f.readline()
i = int(s.strip())
except IOError as (errno, strerror):
print "I/O error({0}): {1}".format(errno, strerror)
except ValueError:
print "Could not convert data to an integer."
except:
print "Unexpected error:", sys.exc_info()[0]
raise
