在python中使用回溯记录异常 [英] Log exception with traceback in python

问题描述

如何记录 Python 错误?

How can I log my Python errors?

try:
    do_something()
except:
    # How can I log my exception here, complete with its traceback?

推荐答案

使用 logging.exception 来自 except: 处理程序/块，用于记录当前异常以及跟踪信息，并附加一条消息.

Use logging.exception from within the except: handler/block to log the current exception along with the trace information, prepended with a message.

import logging
LOG_FILENAME = '/tmp/logging_example.out'
logging.basicConfig(filename=LOG_FILENAME, level=logging.DEBUG)

logging.debug('This message should go to the log file')

try:
    run_my_stuff()
except:
    logging.exception('Got exception on main handler')
    raise

现在查看日志文件，/tmp/logging_example.out:

DEBUG:root:This message should go to the log file
ERROR:root:Got exception on main handler
Traceback (most recent call last):
  File "/tmp/teste.py", line 9, in <module>
    run_my_stuff()
NameError: name 'run_my_stuff' is not defined
