如何打印程序退出/程序终止/退出错误的原因？

Question

I managed to catch the termination with:

atexit.register(exitHandler)

But how to print out what happened on that point? I want to see if the program aborts due to an error, due to Crtl-C or normal stopping...

Answer 1

It's not the complete solution - but you could wrap code in try except

try:
    YOUR CODE HERE

except Exception as e:
    print(e)

Answer 2

You should catch KeyboardInterrupt for Ctrl-CEg:

import sys


try:
    # your code
except KeyboardInterrupt:
    sys.exit('Abort by user interrupt')
except Exception as exc:
    sys.exit(f'Abort on error: {exc}')
