Question

因此，我的程序为用户提供了创建文件夹和子文件夹的权限... 到目前为止，我设法使其在默认目录中创建了该文件夹，但是当我尝试创建子文件夹时，这对我来说变得很复杂...我已经尝试解决了几个小时，但是我不能。如果有人可以帮助我，那将是非常愚蠢的事情！！！他们是对代码的注释，以帮助更好地理解。谢谢

在阅读您提供的代码后，我注意到您在同一级别创建了文件夹和子文件夹。

要创建一个文件夹，假设您的沙箱为“ F：\ Test”，请编写以下代码：

 os.chdir('F:\\Test') # you changed your current directory to 'F:\\Test' (chdir means change directory equivalent to cd in linux shell)
 os.mkdir(folder) # you created a folder

 ... # after a few lines

 os.chdir('F:\\Test') # you're still in the same directory
 os.mkdir(subfolder) # folder and subfolder are thus created under the same directory

由于在创建子文件夹之前没有更改当前目录，因此最终会得到两个处于同一级别的文件夹。这是我的建议。

子文件夹必须位于先前在'F：\ Test'下创建的文件夹内。

 os.chdir('F:\\Test') #changed the current directory to 'F:\Test'
 folder = 'Folder' # the name of the folder
 os.mkdir(folder)  # creates a folder inside 'F:\Test' and you get 'F:\Test\Folder'

 subfolder = 'Subfolder'

 # You need to concatenate 'F:\\Test' with the parent folder of your subfolder. I assume that you picked the previously created folder.

 os.chdir('F:\\Test\\' + folder) # changed the current directory to 'F:\Test\Folder'
 os.mkdir(subfolder) # creates a folder inside 'F:\Test\Folder' and you get 'F:\Test\Folder\Subfolder'

有没有简单的方法来获取子文件夹的路径？
