os.walk()

os.walk() 方法用於通過在目錄樹中游走輸出在目錄中的檔名，向上或者向下。

os.walk(top[, topdown=True[, onerror=None[, followlinks=False]]])

top 為要遍歷的目錄：

topdown = True，優先遍歷top目錄，再遍歷子目錄，可選引數

onerror -- 可選， 需要一個 callable 物件，當 walk 需要異常時，會呼叫。

followlinks -- 可選， 如果為 True，則會遍歷目錄下的快捷方式(linux 下是 symbolic link)實際所指的目錄(預設關閉)。

得到的是一個元組(root,dirs,files)

root  當前遍歷到的目錄

dirs  當前目錄下的子目錄，是一個list

files 當前目錄下的檔案，是一個list

os.path.join()

將多個路徑組合後返回

語法：os.path.join(path1[,path2[,path3[,...[,pathN]]]])

注意：第一個絕對路徑之前的引數將會被忽略
