python读取系统信息的一些方法
最主要是的platform模块：
# 来自jb51.cc
>>> import platform
>>> platform.version()
'#1 SMP Fri Feb 22 00:31:26 UTC 2013'
>>> platform.platform()
'Linux-2.6.32-358.el6.x86_64-x86_64-with-centos-6.4-Final'
>>> platform.system()
'Linux'
>>> platform.machine()
'x86_64'
>>> platform.python_build()
('r266:84292','Feb 22 2013 00:00:18')
>>> platform.python_version()
'2.6.6'
>>> platform.release()
'2.6.32-358.el6.x86_64'
>>> platform.uname()
('Linux','localhost.localdomain','2.6.32-358.el6.x86_64','#1 SMP Fri Feb 22 00:31:26 UTC 2013','x86_64','x86_64')
>>> platform.architecture()
('64bit','ELF')获取用户名：
# 来自jb51.cc
>>> import getpass
>>> getpass.getuser()
'root'获取环境变量：
# 来自jb51.cc
>>> 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')
/root
>>> print os.getenv('USER')
root
>>> 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_uid=0,pw_gid=0,pw_gecos='root',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
