【Python】批量更改文件名中相同部分的内容

import os

def ModifyFileName(filepath, originalname, modifyname):
    filename = os.path.basename(filepath)
    if originalname in filename:
        replacename = filename.replace(originalname, modifyname)
        replacepath = os.path.dirname(filepath)+'\'+replacename
        try:
            os.rename(filepath, replacepath)
            print(filename + " 已修改为：" + replacename)
        except :
            print(filename + "文件路径不存在")

def ModifyAll(dirpath, originalname, modifyname):
    for root, dirs, files in os.walk(dirpath):
        for file in files:
            ModifyFileName(os.path.join(root, file),originalname,modifyname)
    print("已全部修改")



if __name__ == '__main__':

    dirpath = "文件夹路径"
    originalname = "需要修改的部分"
    modifyname = "更改后的内容"
    print("正在执行中")
    ModifyAll(dirpath, originalname, modifyname)
