1.直接打印错误

  1. try:
  3.     # your code
  5. except KeyboardInterrupt:
  7.     print(“quit”)
  9. except Exception as ex:
  11.     print(“出现如下异常%s”%ex)

如下例子

  1. try:
  2. 2/0
  3. except Exception as e:
  4. print(e)

结果为：division by zero

2.用traceback模块打印

上述结果看不到具体错误的信息，如行数啥的，不方便调试的时候定位，因此也可以用traceback模块，方便调试

  1. import traceback
  2. try:
  3. 2/0
  4. except Exception as e:
  5. traceback.print_exc()

结果为：

Traceback (most recent call last):
File “c:\Users\Administrator\Desktop\test1.py”, line 3, in <module>
2/0
ZeroDivisionError: division by zero

ps：上述traceback.print_exc()是直接打印错误

还可以用traceback.format_exc()返回字符串，可将错误信息保存在文档日志中

可以说traceback.print_exc()等同于print traceback.format_exc()
