操作系统相关
system() : 操作系统类型(见例)
version(): 操作系统版本
release(): 操作系统发布号, 例如win 7返回7, 还有如nt, 2.2.0之类.
platform(aliased=0, terse=0): 操作系统信息字符串,扥与system()+win32_ver()[:3]
win32_ver(release=”, version=”, csd=”, ptype=”): win系统相关信息
linux_distribution(distname=”, version=”, , supported_dists=(‘suse’, ‘debiaare’, ‘yellowdog’, ‘gentoo’, ‘unitedlinux’, ‘turbolinux’), full_distribution_name=1): linux系统相关信息
dist(distname=”, version=”, , supported_dists=(‘suse’, ‘debian’, ‘fedora’, ‘redhat’, ‘centos’, ‘mandrake’, ‘mandriva’, ‘rocks’, ‘slackware’, ‘yellowdog’, ‘gentoo’, ‘unitedlinux’, ‘turbolinux’)): 尝试获取linux os发布版本信息.返回(distname,version,id). dist是发布版本的意思.
mac_ver(release=”, versioninfo=(‘’, ‘’, ‘’), machine=”): mac版本
java_ver(release=”, vendor=”, vminfo=(‘’, ‘’, ‘’), osinfo=(‘’, ‘’, ‘’)): java版本
libc_ver(executable=r’c:\python27\python.exe’, lib=”, version=”, chunksize=2048): libc版本,linux相关吧.
以上相应版本查询的返回元组和其形参对应.

‘root’
获取环境变量：
>>> import os
>>> import pwd
>>> os.environ[‘lang’]
‘en_us.utf-8’
>>> print os.getenv(‘lang’)
en_us.utf-8
>>> print os.getenv(‘pwd’)
/root
>>> print os.getenv(‘home’)

>>> print os.getenv(‘hostname’)
localhost.localdomain
>>> print os.getenv(‘shell’)
/bin/bash
>>> pwd.getpwuid(os.getuid())
pwd.struct_passwd(pw_name=’root’, pw_passwd=’x’, pw_uroot’, pw_dir=’/root’, pw_shell=’/bin/bash’)
>>> pwd.getpwuid(os.getuid())[0] #获得用户名
‘root’
>>> pwd.getpwuid(os.getuid())[5] #获得家目录
‘/root’
>>> pwd.getpwuid(os.getuid())[6] #获得shell
‘/bin/bash’
还有个os.environ.get，会返回所有环境变量为一个字典
