Python 通过traceback追溯异常信息

1. 导入traceback包

   import traceback
   

2. 自定义函数

   def func_3():
       return 1 / 0
   
   
   def func_2():
       func_3()
   
   
   def func_1():
       func_2()
   

3. 捕捉异常

   try:
       func_1()
   except Exception as e:
       traceback_info = traceback.format_exc()
       print("===traceback_info===")
       print(traceback_info)
       print("===traceback_info===")
   
   

   打印追溯异常信息：

   ===traceback_info===
   Traceback (most recent call last):
