python批量修改文件后缀示例代码分享

ipad的goodreader对js文件支持不太好,虽然可以读取它但总是无法退出,回不了goodreader的主界面,因此我需要把js文件批量变成纯文本。基于这个目的,我搞了下面一个小应用:

代码如下:

# -*- coding:utf-8 -*-import osdef rename(): path = raw_input(“请输入要处理的文件夹路径”) print path old_ext = “.”+raw_input(“请输入要处理的文件类型”) print old_ext new_ext = “.”+raw_input(“请输入你想变成的文件类型”) print new_ext for (path, dirs, files) in os.walk(path):#遍历目录树 for filename in files: ext = os.path.splitext(filename)[1] #取得文件类型,注意它还带着点号 print ext; if(ext == old_ext): print “—————-” newname = filename.replace(old_ext, new_ext) oldpath = path + “\\” + filename newpath = path + “\\” + newname try: os.rename(oldpath, newpath) except baseexception, e: print(str(e))if __name__ == ‘__main__’: rename()
