如何获取python中发生异常或错误的行号?

试试这个:

import logging
logger = logging.getLogger(__name__)

try:
    specialization_object = Specialization.objects.get(name="My Test Specialization")
except Exception as ex:
    logger.info(ex, exc_info=True) # exc_info will add traceback

如果你因为任何原因不能使用日志记录,有一个标准的包 traceback ,您可以执行以下操作:

traceback.print_exc(file=sys.stdout)

我刚刚想出了一个简单的解决办法:

import traceback
try:
    specialization_object = Specialization.objects.get(name="My Test Specialization")
except Exception as ex:
    print(traceback.format_exc())
