Question

目前我的文件夹中有38个子文件夹测试子文件夹名称从 01 开始到 38 。每个子文件夹有2个wav文件，这些文件是随机命名的，我想正确地按顺序重命名它。例如：子文件夹 01 有wav文件我的录音＃1 和我的录音＃6 ，我希望将它们重命名为 01_test_01 和 01_test_02 所以最后一个文件夹 38 应该包含文件 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)

然而，当执行os.rename时，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'

最喜欢它试图重命名同一个文件两次，而不是从子文件夹重命名每个文件一次

输出：

Answer 1

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，因为你提到了Each sub folder has 2 wav files。

第二个for循环（for file in files:）和内部while循环（while y < 3:）实际上是导致错误。第二个for循环已经迭代了所有文件，所以，你不需要那个内部while循环。

在没有内部while循环的情况下修改程序，如下所示。

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（在我的场景中）：

./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

Answer 2

你有内部while循环导致问题，它将多次使用相同的filepath，将其替换为if条件，如下所示：

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)

使用子文件夹标记重命名子文件夹中的文件
