目前我的文件夹test 中有 38个子文件夹子文件夹名称从01到38。每个子文件夹有 2 个随机命名的 wav 文件，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，我希望它们被重命名为01_test_01和01_test_02所以最后一个文件夹38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，当 os.rename 执行时，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'
最有可能它试图重命名同一个文件两次，而不是从子文件夹中重命名每个文件一次
输出：

您有内部while循环，这会导致问题，它将filepath多次使用相同的内容，将其替换为如下if条件：
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)
