python的 for dirpath, dirnames, filenames in os.walk(rs_path):

假设这三个目录三个文件放在 rs_path=d:/gmz 目录里面。那么要获取所有的文件路径，可以用如下方式

for parentpath, dirnames, filenames in os.walk(rs_path):

　　for filename in filenames:
　　print "filePath:" + parentpath + "/" + filename

 

 

//这里总共会遍历四次，parentpath包含了所有文件父目录的可能即：

d:/gmz/Battlefield

d:/gmz/card

d:/gmz/font

d:/gmz  

　

2 多行注释可以 定义一个不用的变量 _ggmz=‘‘‘  这里放置需要注释的内容 ‘‘‘ (重点是三个引号标识注释)

 

//基本使用
