os.rename(src, dst)

将名称 scr 修改为 dst

无返回值

文件或目录同理

2 语法：os.rename()

2.1 相对路径

import os# 文件相对路径
# print(os.getcwd())# 原文件名
old_name = 'old.txt'# 新文件名
new_name = 'new.txt'# 重命名文件(目录同理)
os.rename(old_name, new_name)

2.2 绝对路径

import os# 文件绝对路径
old_name = r'C:\Users\Administrator\Desktop\old.txt'# 目录
dir_name = os.path.dirname(old_name)# 文件
# base_name = os.path.basename(old_name)# 新文件名
new_name = os.path.join(dir_name, 'new.txt')# 重命名文件(目录同理)
os.rename(old_name, new_name)
