系统未异常退出

Question

我正在调用打开文本文件的函数。如果出现异常，我想退出整个程序。代码如下：

def get_words():
    print("File:",FILENAME)

    try:
        words = open(FILENAME, 'r')
    except FileNotFoundError:
        print("File {} not found.".format(FILENAME))
        sys.exit(1)
    except Exception as err:
        print("Unexpected Error opening {}".format(FILENAME))
        sys.exit(1)
    else:
        with words:
            words2 = words.read()
            wordlist = words2.split(" ")

            words.close()
            return wordlist
    pass

我在下面的代码中调用这个函数：

words = get_words()

当我执行此操作时，出现 During Handling of the above exception, another Exception occured 错误。请分享为什么这么简单的事情会导致错误。完整回溯：

ERROR:root:Internal Python error in the inspect module.
Below is the traceback from this internal error.

这应该可以解决问题。

import sys
import os

def get_words():

    print("File:",FILENAME)
 
    if os.path.exists(FILENAME):
        with open(FILENAME, 'r') as f:
            words2 = f.read()

        return words2.split(" ")
    else:
        print("File {} not found.".format(FILENAME))
        sys.exit()

words = get_words()

系统未异常退出

System not exiting in exception
