在某些系统上,主机名是在环境中设置的。如果是这样的话,操作系统模块可以通过os.getenv把它从环境中拉出来。例如,如果HOSTNAME是包含你想要的内容的环境变量,下面将得到它:

import os
system_name = os.getenv('HOSTNAME')

Update: As noted in the comments, this doesn't always work, as not everyone's environment is set up this way. I believe that at the time I initially answered this I was using this solution as it was the first thing I'd found in a web search and it worked for me at the time. Due to the lack of portability I probably wouldn't use this now. However, I am leaving this answer for reference purposes. FWIW, it does eliminate the need for other imports if your environment has the system name and you are already importing the os module. Test it - if it doesn't work in all the environments in which you expect your program to operate, use one of the other solutions provided.

我需要在PyLog conf文件中使用的PC的名称,并且套接字库不可用,但操作系统库可用。

对于Windows,我使用的是:

os.getenv('COMPUTERNAME', 'defaultValue')

哪里defaultValue是一个字符串,以防止None返回

从至少python >= 3.3:

你可以使用字段nodename,避免使用数组索引:

os.uname().nodename

虽然,甚至os的文档。Uname建议使用socket.gethostname()

使用socket.getfqdn()获取完全限定的主机名

import socket

print socket.getfqdn()

Socket.gethostname()可以做什么
