Python判断操作系统类型

本文作者为吕浪（Victor Lv），转载请注明出处。

python(2.7) check the os type running on:

1. use sys.platform:

windows:

    >>> import sys
    >>> sys.platform
    >>> 'win32'

linux

    >>> import sys
    >>> sys.platform
    >>> 'linux2'

2. use platform.system():

windows:

    >>> import platform
    >>> platform.system()
    >>> 'Windows'

linux:

    >>> import platform
    >>> platform.system()
    >>> 'Linux'

3. Judge the os type:

We can use "=="(equal) to judge whether the os is window or linux, or we can use string.startwith() function to check it:

    if sys.platform.startswith('freebsd'):
        # FreeBSD-specific code here...
    elif sys.platform.startswith('linux'):
        # Linux-specific code here...
