重命名与子标签的子文件夹中的文件

Question

目前，我有我的文件夹中的子文件夹38测试的子文件夹名称开始从到。每个子文件夹都有2个随机命名的wav文件，我想正确并顺序地重命名它。 例如： 子文件夹有wav文件我记录＃1和我的记录＃6，我希望他们改名为01_test_01和01_test_02所以最后一个文件夹应该有文件38_test_01和38_test_02

下面是我的代码

import os 
name = 'test' 

rootdir = r'C:\Users\kushal\Desktop\final_earthquake\demonstration_sikkim\wav\test' 

for subdir, dirs, files in os.walk(rootdir): 
    for file in files: 

     filepath = subdir+os.sep +file 
     if filepath.endswith('.wav'): 

      split_dir = subdir.split(os.sep) 

      f_name, f_ext=(os.path.splitext(file)) 

      new_1 = split_dir[8] 
      y=1 
      while y < 3 : 
       new_name= (new_1 +'_' + 'test_' + str(y).zfill(2) + f_ext) 
       y = y +1 
       print (filepath) 
       print (subdir+os.sep+new_name) 
       os.rename(filepath, subdir+os.sep+new_name) 

但是在执行时os.rename我收到以下错误

Traceback (most recent call last): 
    File "C:\Users\kushal\Desktop\final_earthquake\sikkim_demo\demo_sikkim_victor\sort_inner_wav.py", line 23, in <module> 
    os.rename(filepath, subdir+os.sep+new_name) 
FileNotFoundError: [WinError 2] The system cannot find the file specified: 'C:\\Users\\kushal\\Desktop\\final_earthquake\\demonstration_sikkim\\wav\\test\\01\\My recording #5.wav' -> 'C:\\Users\\kushal\\Desktop\\final_earthquake\\demonstration_sikkim\\wav\\test\\01\\01_test_02.wav' 

大多数LIKEY它试图重新命名相同的文件，而不是两次从子

输出一次重命名每个文件：

C:\Users\kushal\Desktop\final_earthquake\demonstration_sikkim\wav\test\01\My recording #1.wav 
C:\Users\kushal\Desktop\final_earthquake\demonstration_sikkim\wav\test\01\01_test_01.wav

Answer 1

你有内部while循环，导致问题，它会使用相同的filepath多次，if条件这样的替换：

import os 
name = 'test' 

rootdir = r'C:\Users\kushal\Desktop\final_earthquake\demonstration_sikkim\wav\test' 

for subdir, dirs, files in os.walk(rootdir): 
    y=1 
    for file in files: 
     filepath = subdir+os.sep +file 
     if filepath.endswith('.wav'): 

      split_dir = subdir.split(os.sep) 
      print split_dir 

      f_name, f_ext=(os.path.splitext(file)) 

      new_1 = split_dir[7] 

      new_name= (new_1 +'_' + 'test_' + str(y).zfill(2) + f_ext) 
      y+=1 
      if y>3: 
       break 
      print (filepath) 
      print (subdir+os.sep+new_name) 
      os.rename(filepath, subdir+os.sep+new_name) 

Answer 2

你有两个for循环，这是可以理解的，但为什么有一个内部while循环？我想，你添加了while循环，因为你提到过，Each sub folder has 2 wav files。

第二个for循环（for file in files:）和inner while循环（while y < 3:）实际上是导致错误。第二个for循环已经遍历所有的文件，所以，你不需要内部的while循环。

如下修改程序而不使用inner while循环。

import os 
rootdir = './test' 

for subdir, dirs, files in os.walk(rootdir): 
    y = 1 
    for file in files: 
     filepath = subdir + os.sep + file 
     if filepath.endswith('.wav'): 
      split_dir = subdir.split(os.sep) 
      f_name, f_ext = os.path.splitext(file) 
      new_name= split_dir[len(split_dir) - 1] +'_' + 'test_' + str(y).zfill(2) + f_ext 
      y = y + 1 
      print (filepath) 
      print (subdir + os.sep + new_name) 
      os.rename(filepath, subdir + os.sep + new_name) 

它输出（在我的情况）：

./test\01\yy.wav 
./test\01\01_test_01.wav 
./test\01\xx.wav 
./test\01\01_test_02.wav 
./test\02\yy.wav 
./test\02\02_test_01.wav 
./test\02\xx.wav 
./test\02\02_test_02.wav
