loguru

@logger.catch():只会捕捉到未except的异常，并中断程序

未处理除0异常：

from loguru import  logger

@logger.catch()
def demo():
    # try:
    a = 1 / 0
    # except Exception as e:
    #     logger.error(e)
    print('11111111111111111')
if __name__ == '__main__':
    demo()

print语句并不会执行
out:

2023-01-03 16:39:35.991 | ERROR    | __main__:<module>:12 - An error has been caught in function '<module>', process 'MainProcess' (11164), thread 'MainThread' (16832):

  File "D:\soft\pythonProject\demo\demo.py", line 7, in demo
    a = 1 / 0

ZeroDivisionError: division by zero

except 处理除0异常后， @logger.catch() 不会生效：

from loguru import  logger

@logger.catch()
def demo():
    try:
        a = 1 / 0
    except Exception as e:
        logger.error(e)

out:

2023-01-03 16:42:39.583 | ERROR    | __main__:demo:8 - division by zero

总结：

@logger.catch() 用来打印没有预料到异常信息，方便排查问题
