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.

使用套接字及其gethostname()功能。这将得到运行Python解释器的计算机的主机名:

import socket
print(socket.gethostname())

这两个都是非常可移植的:

import platform
platform.node()

import socket
socket.gethostname()

任何使用HOST或HOSTNAME环境变量的解决方案都不能移植。即使它在您的系统上运行时可以工作，但在cron等特殊环境中运行时可能无法工作。

你可能会加载操作系统模块，所以另一个建议是:

import os
myhost = os.uname()[1]

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()

如果我没猜错，你是在找插座。gethostname功能:

>> import socket
>> socket.gethostname()
