python实用一技--重命名
某宝给小朋友买了个电子琴学习光盘,想放到ipad播放,但光盘上的文件为dat格式,需转为msp格式,以下为转换代码(其实就是重命名文件):
#encoding=utf-8 """ 将VCD的DAT文件命令为mpg文件 """ import os path = r"E:\家庭&生产\B\MPEGAV2" filelist = os.listdir(path) count=0 def getNewName(oldfile): #旧名改新名 name = oldfile.split(‘.‘)[0] return name + ".mpg" for file in filelist: # print(file) if "DAT" in file: newname = getNewName(file) old_file = os.path.join(path, file) new_file = os.path.join(path, newname) print("rename %s to %s" %(old_file,new_file)) os.rename(old_file, new_file) #重命名核心功能函数 else: print("not dat file")
