[Coding note] used in python traceback exception information is recorded

Sometimes, we want to throw exception information is written in python program storage medium, this time we can use the package to read exception traceback information:

import traceback

try:
    raise Exception("发现异常")            
except Exception:
    print("追溯异常：\n"+'---'*20)
    print(traceback.format_exc())

operation result:

追溯异常：

Traceback (most recent call last):
  File "<ipython-input-3-a0443d867f20>", line 4, in <module>
    raise Exception("发现异常")
Exception: 发现异常
