PermissionError:Python 中的 [Errno 13]

问题描述

刚开始学习一些 Python，我遇到了如下所述的问题:

Just starting to learn some Python and I'm having an issue as stated below:

a_file = open('E:Python Win7-64-AMD 3.3Test', encoding='utf-8')

Traceback (most recent call last):
  File "<pyshell#9>", line 1, in <module>
    a_file = open('E:Python Win7-64-AMD 3.3Test', encoding='utf-8')
PermissionError: [Errno 13] Permission denied: 'E:\Python Win7-64-AMD 3.3\Test

似乎是文件权限错误，如果有人能发光，将不胜感激.

Seems to be a file permission error, if any one can shine some light it would be greatly appreciated.

注意:不确定 Python 和 Windows 文件如何工作，但我以管理员身份登录到 Windows，并且该文件夹具有管理员权限.

我已尝试将 .exe 属性更改为以管理员身份运行.

I have tried changing .exe properties to run as Admin.

推荐答案

什么时候做；

a_file = open('E:Python Win7-64-AMD 3.3Test', encoding='utf-8')

...您正在尝试将 目录 作为文件打开，这可能(并且在大多数非 UNIX 文件系统上)会失败.

...you're trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.

你的另一个例子；

a_file = open('E:Python Win7-64-AMD 3.3Testa.txt', encoding='utf-8')

如果您只有 a.txt 的权限，应该可以正常工作.您可能希望使用原始(r-prefixed)字符串，以确保您的路径不包含任何转义字符，如 将被转换为特殊字符.

should work well if you just have the permission on a.txt. You may want to use a raw (r-prefixed) string though, to make sure your path does not contain any escape characters like that will be translated to special characters.

a_file = open(r'E:Python Win7-64-AMD 3.3Testa.txt', encoding='utf-8')
