Python os库 批量重命名文件或修改文件格式为jpg

代码如下：

import os

def listFileContent(path):
    for filename in os.listdir(path):
        file_path=os.path.join(path,filename)
        print(filename)

def renameFiles(path):
    for filename in os.listdir(path):
        file_path=os.path.join(path,filename)
        os.rename(file_path,file_path+".jpg")

renameFiles("H:/EclipseForJavaEE/learningImages/PMSysBasedOnSSM")
listFileContent("H:/EclipseForJavaEE/learningImages/PMSysBasedOnSSM")
