打印Python異常信息的幾種方式
1 簡(jiǎn)單的異常信息
try:
a = 1/0
except Exception as e:
print(e)
打印最簡(jiǎn)單的message信息：
division by zero
2 更完整的信息
import traceback
try:
a = 1/0
except Exception as e:
print('str(e):\t', e)
print('repr(e):\t', repr(e))
print('traceback.format_exc():\n%s' % traceback.format_exc()) #字符串
traceback.print_exc() #執(zhí)行函數(shù)
輸出：
str(e): division by zero
repr(e): ZeroDivisionError('division by zero')
traceback.format_exc():
Traceback (most recent call last):
File "/Users/ace/Play/test/異常信息.py", line 4, in <module>
a = 1/0
ZeroDivisionError: division by zero
Traceback (most recent call last):
File "/Users/ace/Play/test/異常信息.py", line 4, in <module>
a = 1/0
ZeroDivisionError: division by zero
traceback.format_exc()和traceback.print_exc()都可以打印完整的錯(cuò)誤信息
traceback.format_exc()返回值為字符串
traceback.print_exc()是一個(gè)執(zhí)行函數(shù)用踩，直接在控制臺(tái)打印錯(cuò)誤信息
