python实现文件批量重命名

import os


def reName(dirname):
 count = 0
 for cur_file in os.listdir(dirname):
 count += 1
 oldDir = os.path.join(dirname, cur_file) 
 filetype = os.path.splitext(cur_file)[1] # 文件类型
 newDir = os.path.join(dirname, str(count) + filetype) # 新文件
 os.rename(oldDir, newDir)
 print(oldDir, newDir)


if __name__ == "__main__":
 dirname = r""#文件夹路径
 reName(dirname)
