Python处理任何异常都会产生错误KeyboardInterrupt

Question

代码如下：

try:
    input() # I hit Ctrl+C
except Exception as e:
    print(str(e))

这是回溯：

Traceback (most recent call last):
  File "C:\Users\User\Desktop\test.py", line 2, in <module>
    input()
KeyboardInterrupt

Answer 1

当您想抓住KeyboardInterrupt时，请明确：

try:
    input() # I hit Ctrl+C
except Exception as e:
    print(str(e))
except KeyboardInterrupt :
    print 'ok, ok, terminating now...'

Answer 2

sudo apt-get install openjdk-8-jdk 不是Exception，而只是BaseException，因此您的KeyboardInterrupt没有处理它：

except

处理>>> issubclass(KeyboardInterrupt, Exception) False >>> issubclass(KeyboardInterrupt, BaseException) True 可让您访问任何异常，但不建议这样做：

BaseException
