ใช้ sys.exc_info() คืน tuple (type, value, traceback)
- type: exception type
- value: error message
- traceback: stack snapshot
ตัวอย่าง: ดึง type, filename, line number
import sys, os
try:
raise NotImplementedError("No error")
except Exception as e:
exc_type, exc_obj, exc_tb = sys.exc_info()
fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]
print(exc_type, fname, exc_tb.tb_lineno)
