今天想往MP3下點音樂，但是滿了，想把里面不喜歡的刪了，但是音樂都在各個文件夾下，于是，我希望所有的音樂文件可以移動到一個層面，以供我按照音樂專輯的封面來挑選要刪哪個，于是就想寫個程序來做一下整理，想想用我擅長的Java來寫吧，但是沒什么意思，想到一直想學Python，何不拿Python練練手呢？

于是：安裝環境：2.5，3.4，2.7，我有3個版本，在練習的時候發現有些語法問題，我猜可能是版本的問題，于是換了3個版本，最后用了最穩定的2.7。IDE使用的是Eclipse。

通過查看簡單的Python語法說明：http://pythonprogramminglanguage.com/以及一個API文檔https://docs.python.org/2/library/index.html，勉勉強強的把這個程序寫出來了：

''' @author: Sahadev ''' import os import shutilpath = "H:\Music\CloudMusic"; listdir1 = os.listdir(path) i = len(listdir1) print i for j in range(i):print(listdir1[j])file = path + '\\' + listdir1[j]isdir = os.path.isdir(file)if isdir:childPath = os.listdir(file)len1 = len(childPath)for k in range(len1):result = file + '\\' + childPath[k]childFileName = path + '\\' + childPath[k]print childFileNameos.rename(result, childFileName)if len1 == 0:os.removedirs(file)

剛開始寫的程序，貼出來也沒有什么注釋，可能代碼只有我自己知道了，嗯，就是個見證。

再貼上控制臺日志：
