python os讀取文件

<pre class="markdow-doc">

import os


def dir_walk(dirname):
    filelist = []
    for root, dirs, files in os.walk(dirname):#root dir files 都是類 
        for name in dirs:
            filelist.append(os.path.join(root, name))
    print(filelist)
    return filelist


dirname = r'D:\BaiduMusic\virus'#r是轉義，要不就用雙斜杠
print(dir_walk(dirname))
