【小工具】python：批量修改文件夹下的文件名

工具使用场景：需要将文件夹下的所有文件按照names里的value内容修改掉，如果不存在，则根据模块进行复制。

import os
import shutil

names = 'key01,value01;key02,value02;key03,value03'
names_dict = {k: v for k, v in (item.split(',') for item in names.split(';'))}

path = r'C:\Users\xxx'
for filename in os.listdir(path):
    for k, v in names_dict.items():
        if v in filename:
            new_name = k + v + '.docx'
            # new_name = k + v  #这里处理文件夹
            old_path = os.path.join(path, filename)
            new_path = os.path.join(path, new_name)
            if os.path.exists(new_path):
                continue
            os.rename(old_path, new_path)
            print(f"重命名: {filename} -> {new_name}")
for k, v in names_dict.items():
    isEx = False
    for filename in os.listdir(path):
        if v in filename:
            isEx = True
    if isEx == False:
        old_path = os.path.join(path, '模版.docx')
        new_path = os.path.join(path, k + v + ' 补.docx')
        shutil.copy(old_path, new_path)
        # old_path = os.path.join(path, '模板') #这里处理文件夹
        # new_path = os.path.join(path, k + v + ' 补')
        # shutil.copytree(old_path, new_path)
