Python中使用platform模块获取系统信息的用法教程

时间：2022-12-02 22:05:58

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.
  • platform.architecture()

>>> import getpass
>>> getpass.getuser()

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
