计算文件名的字符并重命名

Question

import os
import glob
from Tkinter import Tk
from tkFileDialog import askdirectory


fileDir = askdirectory()
print(fileDir)
#newfileDir=fileDir.replace('/','\\')

files =  glob.glob("*.ac3")
print files

cnt = 0
for f in files:
   if len(f) < 3 + 4:
      os.rename(f, str(cnt)+f)
      cnt += 1
      print("renamed " + f) 

我需要计算小于3个字符的文件名的字符长度，并将文件名重命名为numeric。

试试这段代码：

import glob
import os

files =  glob.glob("*.ac3")

cnt = 0
for f in files:
   if len(f) < 3 + 4: # 4 is the length of the extension ".ac3"
      os.rename(f, str(cnt)+f)
      cnt += 1
      print("renamed " + f)
