如何在纯Python中表达这个Bash命令

unm*_*ted 1 python shell language-comparisons

我在一个有用的Bash脚本中有这一行,我没有设法将其转换为Python,其中'a'是用户输入的存档天数值:

find ~/podcasts/current -mindepth 2 -mtime '+`a`+' -exec mv {} ~/podcasts/old \;

我熟悉最常用的跨平台元素的os.name和getpass.getuser.我也有这个函数来生成相当于〜/ podcasts/current的所有文件的全名列表:

def AllFiles(filepath, depth=1, flist=[]):
    fpath=os.walk(filepath)
    fpath=[item for item in fpath]
    while depth < len(fpath):
        for item in fpath[depth][-1]:
            flist.append(fpath[depth][0]+os.sep+item)
        depth+=1
    return flist

首先,必须有更好的方法,任何建议欢迎.无论哪种方式,例如,"AllFiles('/ users/me/music/itunes/itunes music/podcasts')"在Windows上提供相关列表.据推测,我应该能够查看此列表并调用os.stat(list_member).st_mtime并将所有超过特定数字的内容移动到存档中; 我有点卡在那一点上.

当然,任何具有bash命令简洁性的东西也会很有启发性.
