批量化更改文件名称

import os
path= 'D:\\yucai\\错号数据集//'#待修改的文件文件夹的绝对路径
for dirpath, dirnames, filenames in os.walk(path):
    filenames = filenames
num = 1
for name in filenames:
    print(name)
    Olddir=os.path.join(path,name)
    if os.path.isdir(Olddir):#判断是否真的需要被修改
        continue
    new = os.path.join(path,+ str(num) + '.png')#更改名称后的文件的名字
    print(new)
    os.rename(Olddir,new)
    num += 1
