這里我們整理了Python中使用platform模塊獲取系統(tǒng)信息的用法教程,包括操作系統(tǒng)與Python環(huán)境以及系統(tǒng)的環(huán)境變量等信息的獲取方法:

操作系統(tǒng)相關(guān)

system() : 操作系統(tǒng)類型(見例)
version(): 操作系統(tǒng)版本
release(): 操作系統(tǒng)發(fā)布號(hào), 例如win 7返回7, 還有如NT, 2.2.0之類.
platform(aliased=0, terse=0): 操作系統(tǒng)信息字符串,扥與system()+win32_ver()[:3]
win32_ver(release=’’, version=’’, csd=’’, ptype=’’): win系統(tǒng)相關(guān)信息
linux_distribution(distname=’’, version=’’, id=’’, supported_dists=(‘SuSE’, ‘debiaare’, ‘yellowdog’, ‘gentoo’, ‘UnitedLinux’, ‘turbolinux’), full_distribution_name=1): Linux系統(tǒng)相關(guān)信息
dist(distname=’’, version=’’, id=’’, supported_dists=(‘SuSE’, ‘debian’, ‘fedora’, ‘redhat’, ‘centos’, ‘mandrake’, ‘mandriva’, ‘rocks’, ‘slackware’, ‘yellowdog’, ‘gentoo’, ‘UnitedLinux’, ‘turbolinux’)): 嘗試獲取Linux OS發(fā)布版本信息.返回(distname,version,id). dist是發(fā)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相關(guān)吧.

以上相應(yīng)版本查詢的返回元組和其形參對(duì)應(yīng).

獲取用戶名：

>>> import getpass 
>>> getpass.getuser() 
'root'

獲取環(huán)境變量：

>>> 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] #獲得用戶名
'root'
>>> pwd.getpwuid(os.getuid())[5] #獲得家目錄
'/root'
>>> pwd.getpwuid(os.getuid())[6] #獲得shell
'/bin/bash'

還有個(gè)os.environ.get，會(huì)返回所有環(huán)境變量為一個(gè)字典
