Python中使用platform模块获取系统信息的用法教程_程序人生

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=\’\’, id=\’\’, supported_dists=(‘SuSE\’, ‘debiaare\’, ‘yellowdog\’, ‘gentoo\’, ‘UnitedLinux\’, ‘turbolinux\’), full_distribution_name=1): Linux系统相关信息
dist(distname=\’\’, version=\’\’, id=\’\’, 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.

系统信息

uname(): 返回元组,system, node, release, version, machine, processor.
architecture(executable=r\’c:\\Python27\\python.exe\’, bits=\’\’, linkage=\’\’): 系统架构
machine() : CPU平台,AMD,x86?(见例)
node() : 节点名(机器名,如Hom-T400)
processor() : CPU信息
system_alias(system, release, version): 返回相应元组..没何屌用.

获取用户名：

>>> import getpass 
>>> getpass.getuser() 
\'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\')
/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
