使用模块平台检查可用的测试，并打印出适合您系统的答案:

import platform

print dir(platform)

for x in dir(platform):
    if x[0].isalnum():
        try:
            result = getattr(platform, x)()
            print "platform."+x+": "+result
        except TypeError:
            continue

同样的，....

import platform
is_windows=(platform.system().lower().find("win") > -1)

if(is_windows): lv_dll=LV_dll("my_so_dll.dll")
else:           lv_dll=LV_dll("./my_so_dll.so")

对于Jython，我发现获得操作系统名称的唯一方法是检查os.name Java属性(在WinXP上尝试使用sys, os和平台模块的Jython 2.5.3):

def get_os_platform():
    """return platform name, but for Jython it uses os.name Java property"""
    ver = sys.platform.lower()
    if ver.startswith('java'):
        import java.lang
        ver = java.lang.System.getProperty("os.name").lower()
    print('platform: %s' % (ver))
    return ver

你也可以使用sys。平台，如果你已经导入了sys，你不想导入另一个模块

>>> import sys
>>> sys.platform
'linux2'

这个解决方案适用于python和jython。

模块os_identify.py:

import platform
import os

# This module contains functions to determine the basic type of
# OS we are running on.
# Contrary to the functions in the `os` and `platform` modules,
# these allow to identify the actual basic OS,
# no matter whether running on the `python` or `jython` interpreter.

def is_linux():
    try:
        platform.linux_distribution()
        return True
    except:
        return False

def is_windows():
    try:
        platform.win32_ver()
        return True
    except:
        return False

def is_mac():
    try:
        platform.mac_ver()
        return True
    except:
        return False

def name():
    if is_linux():
        return "Linux"
    elif is_windows():
        return "Windows"
    elif is_mac():
        return "Mac"
    else:
        return "<unknown>" 

像这样使用:

import os_identify

print "My OS: " + os_identify.name()
