今天想往MP3下点音乐，但是满了，想把里面不喜欢的删了，但是音乐都在各个文件夹下，于是，我希望所有的音乐文件可以移动到一个层面，以供我按照音乐专辑的封面来挑选要删哪个，于是就想写个程序来做一下整理，想想用我擅长的Java来写吧，但是没什么意思，想到一直想学Python，何不拿Python练练手呢？

于是：安装环境：2.5，3.4，2.7，我有3个版本，在练习的时候发现有些语法问题，我猜可能是版本的问题，于是换了3个版本，最后用了最稳定的2.7。IDE使用的是Eclipse。

通过查看简单的Python语法说明：http://pythonprogramminglanguage.com/以及一个API文档https://docs.python.org/2/library/index.html，勉勉强强的把这个程序写出来了：

'''

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)

刚开始写的程序，贴出来也没有什么注释，可能代码只有我自己知道了，嗯，就是个见证。

再贴上控制台日志：
