重命名與子標籤的子文件夾中的文件

目前，我有我的文件夾中的子文件夾38測試的子文件夾名稱開始從到。每個子文件夾都有2個隨機命名的wav文件，我想正確並順序地重命名它。例如：子文件夾有wav文件我記錄＃1和我的記錄＃6，我希望他們改名爲01_test_01和01_test_02所以最後一個文件夾應該有文件38_test_01和38_test_02重命名與子標籤的子文件夾中的文件

下面是我的代碼

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)

但是在執行時os.rename我收到以下錯誤

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'

大多數LIKEY它試圖重新命名相同的文件，而不是兩次從子

輸出一次重命名每個文件：

你有內部while循環，導致問題，它會使用相同的filepath多次，if條件這樣的替換：

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)

謝謝Tiny D. – choman

@choman實際上，如果所有的子文件夾只包含兩個文件，你就不需要那個if語句。如果你想修改你的程序的方式，它處理所有子文件夾中的所有文件，那麼你不需要'if'條件。我的解決方案會讓你的程序更加靈活。 –

還有一件事，像'new_1 = split_dir [7]'這樣的陳述是不靈活的，並不是實現你想要的東西的最好方法。你應該使用'new_1 = split_dir [len（split_dir） - 1]'。 –

你有兩個for循環，這是可以理解的，但爲什麼有一個內部while循環？我想，你添加了while循環，因爲你提到過，Each sub folder has 2 wav files。

第二個for循環（for file in files:）和inner while循環（while y < 3:）實際上是導致錯誤。第二個for循環已經遍歷所有的文件，所以，你不需要內部的while循環。

如下修改程序而不使用inner while循環。

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)

它輸出（在我的情況）：

./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
