Python批量删除指定类型的文件

示例如下，这里递归删除文件类型为 meta 的所有文件

#coding=utf-8  
  
import os

path = 'F:\\HelloWorld\\'
		
def del_files(dir,topdown=True):  
    for root, dirs, files in os.walk(dir, topdown):  
        for name in files:  
            pathname = os.path.splitext(os.path.join(root, name))  
            if (pathname[1] == ".meta"):  
                os.remove(os.path.join(root, name))  
                print(os.path.join(root,name))  

del_files(path)
