python - 如何打印嵌套循环的异常？

Question

我想打印从内部尝试到外部尝试捕获的所有异常语句。有没有办法在不改变内部 try-catch 块的情况下做到这一点

def test_nested_exceptions():
    try:
        try:
            raise AssertionError('inner error ')
        except AssertionError as ae:

            raise AssertionError("error in except")
        finally:
            raise AssertionError("error in finally")
    except AssertionError as e:
        print(e)

Answer 1

您无法访问finally块中的错误对象，但您可以使用模块获取一些详细信息sys，如下所示。

import sys

def test_nested_exceptions():
  try:
    try:
      raise AssertionError('inner error ')
    except AssertionError as ae:
      print(ae)
      raise AssertionError("error in except")
    finally:
      print(sys.exc_info())
      raise AssertionError("error in finally")
  except AssertionError as e:
    print(e)


test_nested_exceptions()
