UNICODEDECODEERROR:读取语言环境配置文件

Question

我有以下文件

In [5]: !cat /usr/bin/locale | head -n 3

我计划将其解码用于阅读

 In [6]: fin = open('/usr/bin/locale', 'r')                                                                             
In [8]: data = fin.read()

    324         self.buffer = data[consumed:]

我如何将内容读取到变量以进行进一步操作。

Answer 1

这是一个二进制可执行文件。它不包含配置。

如果您正在寻找所有受支持的地区，请使用文件/usr/share/i18n/SUPPORTED

如果您正在寻找系统默认场所：（并非所有系统） /etc/local.conf

在python中获取当前用户的语言环境：

import os;
print(os.environ['LANG'])
#prints locale.encoding en_US.UTF8
print(os.environ['LANGUAGE'])
# prints en_US

---

运行语言环境并将其输出输入字符串（在Linux/Unix上最一致）：

import subprocess
locale = subprocess.getoutput("/usr/bin/locale ")

您可以在上述代码中使用任何有效的参数来区域。
