Python输出详细的异常信息 traceback 方式

 举例应用

import yagmail
import traceback
from config.setting import email_info, email_cc, email_to, log


def send_mail(subject, content, files=None):
    try:
        smtp = yagmail.SMTP(**email_info)
        smtp.send(subject=subject, contents=content,
                  to=email_to, cc=email_cc, attachments=files)
    except Exception as e:
        log.error("发送邮件失败+%s" % traceback.format_exc())

traceback的实践

import traceback

try:
    s=1/0
except Exception as e:
    # print(e) #division by zero

    print(traceback.format_exc())
    # Traceback (most recent call last):
    #   File "D:/自动化/python-test/day11/把错误信息变成字符串.py", line 4, in <module>
    #     s=1/0
    # ZeroDivisionError: division by zeroi
