    python中，platform模块给我们提供了很多方法去获取操作系统的信息
    如：
        import platform
        platform.platform()        #获取操作系统名称及版本号，'Linux-3.13.0-46-generic-i686-with-Deepin-2014.2-trusty'
        platform.version()         #获取操作系统版本号，'#76-Ubuntu SMP Thu Feb 26 18:52:49 UTC 2015'
        platform.architecture()    #获取操作系统的位数，('32bit', 'ELF')
        platform.machine()         #计算机类型，'i686'
        platform.node()            #计算机的网络名称，'XF654'
        platform.processor()       #计算机处理器信息，''i686'
        platform.uname()           #包含上面所有的信息汇总，('Linux', 'XF654', '3.13.0-46-generic', '#76-Ubuntu SMP Thu Feb 26 18:52:49 UTC 2015', 'i686', 'i686')

        还可以获得计算机中python的一些信息：
        import platform
        platform.python_build()
        platform.python_compiler()
        platform.python_branch()
        platform.python_implementation()
        platform.python_revision()
        platform.python_version()
        platform.python_version_tuple()
'''

#global var

SHOW_LOG = True

某些时候我们需要获得系统当前的用户名，那么在Pyton中有没有一个可跨平台的方式或者类库支持这一操作呢？

最常用的就是getpass模块

importgetpass

getpass.getuser()

另外也可以用OS模块

import os

os.getenv('username')

python 获取操作系统信息或者用户名
