今天想往MP3下點音樂，但是滿了，想把裡面不喜歡的刪了，但是音樂都在各個資料夾下，於是，我希望所有的音樂檔案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，於是就想寫個程式來做一下整理，想想用我擅長的Java來寫吧，但是沒什麼意思，想到一直想學Python，何不拿Python練練手呢？

於是：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，於是換了3個版本，最後用了最穩定的2.7。IDE使用的是Eclipse。

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 childFileName
            os.rename(result, childFileName)
        if len1 == 0:
            os.removedirs(file)
 

剛開始寫的程式，貼出來也沒有什麼註釋，可能程式碼只有我自己知道了，嗯，就是個見證。
