参考了周蟒的实现, 运行效果如下:

$ python3 解释器.py

相关源码如下, 即改写InteractiveInterpreter.showtraceback方法. 仅为演示之用, 直接用了字符串替换.:

    def showtraceback(self):

        sys.last_type, sys.last_value, last_tb = ei = sys.exc_info()

        sys.last_traceback = last_tb

        try:

            行 = traceback.format_exception(ei[0], ei[1], last_tb.tb_next)

            汉化行 = []

            if sys.excepthook is sys.__excepthook__:

                for 某行 in 行:

                    for 英文 in self.字典:

                        某行 = 某行.replace(英文, self.字典[英文])

                    汉化行.append(某行)

                self.write(''.join(汉化行))

            else:

                # If someone has set sys.excepthook, we let that take precedence

                # over self.write

                sys.excepthook(ei[0], ei[1], last_tb)

        finally:

            last_tb = ei = None

定制sys.excepthook貌似更为合适, 还需研究如何实现.
