Python 找不到现有文件的无法解释的文件

下面是这部分代码中出现的错误。虽然路径有效，但会发生运行时错误。发生了什么事，我怎样才能让它起作用

        for root,dirs,files in os.walk(self.path):
            for f in files :
                if (f.split('.')[1] == "mb"):
                z = utils.executeInMainThreadWithResult(self.contains,(f.split('.')[0]))
                    if not (isinstance(z,NoneType)):
                        cmds.symbolButton(self.arSubCategory + f.split('.')[0], image=(z[1].replace("\\","/")), width = 35,height = 70, c = "h.imp_file(" + "\"" + root.replace("\\","/")  + "/" + f + "\"" + ")")


def contains(self,imageName):
    print 'imageName : ',imageName,'\n'
    for root, dirs, files in os.walk(self.path+"images"):
        for g in files:
            x = re.search(imageName,g)
            if not (isinstance(x, NoneType)):
                print 'g ',root+"/"+g.replace("\\","/"),'\n'
                return (1,(root+"/"+g))

错误：

您对文件夹中的所有文件都有写入权限吗？

建议您使用

os.path

中的函数来操作路径。例如，

os.path.join

和

os.path.splitext
