python - Python如何获取异常或错误发生的行号？

Question

我有一个像这样的 Django ORM 查询:

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

当发生异常时，它会打印“特化匹配查询不存在。”，但不会打印行号。如何追踪异常或错误发生的行号？

Answer 1

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
