Question

有没有办法通过执行文件来获取错误的行号？我们说我有以下代码：

exec(open("test.py").read())

该文件有错误，IDLE弹出以下内容：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python34\lib\tkinter\__init__.py", line 1487, in __call__
    return self.func(*args)
  File "C:\Users\henrydavidzhu\Desktop\Arshi\arshi.py", line 349, in runFile
    exec(open(self.fileName).read())
  File "<string>", line 2, in <module>
TypeError: unsupported operand type(s) for +: 'int' and 'str'

我想知道错误陈述（TypeError: unsupported operand type(s) for +: 'int' and 'str'）和行号。这不是重复，因为我使用的是Python 3，而不是Python 2。

您可以尝试以下代码：

import sys
import traceback

try:
    exec(open('test.py').read())
except Exception as e:
    exc_type, ex, tb = sys.exc_info()
    imported_tb_info = traceback.extract_tb(tb)[-1]
    line_number = imported_tb_info[1]
    print_format = '{}: Exception in line: {}, message: {}'
    print(print_format.format(exc_type.__name__, line_number, ex))

Python 3：有没有办法在使用exec时获取错误的行号和错误语句
