Python 3.5 - Create folder with subfolder under Windows

Question

Is there some elegant way how to create Windows path as follows.

home_dir = ('C:\First\Second\Third')        
if not os.path.exists(home_dir):
    os.mkdir(home_dir)
    print("Home directory %s was created." %home_dir)

I am able to create in single steps "C:\First" then "Second" etc ...

With this code I am getting:

FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:\First\Second\Third'

You should check the existence of a directory path with os.path.isdir:

Return True if path is an existing directory.

os.path.isdir("C:\First\Second\Third")

This will avoid the FileNotFoundError.

Then create the dirs. It looks like so:

home_dir = ('C:\First\Second\Third')        
if not os.path.isdir(home_dir):
    os.makedirs(home_dir)
    print("Home directory %s was created." %home_dir)

For Python 3.2+ you can also use os.makedirs(home_dir, exist_ok=True). This creates all directories in the path, if necessary, and won't raise FileExistsError if the leaf directory already exists.

To create a folder with subfolders use:

os.makedirs(home_dir)

I tried to use os.makidirs before and was getting exactly the same error. I see now that the problem I had was somehow corrupted file with my code. At the momement when I try to execute I am getting (unicode error) cant decode bytes. Anyway, creating New File resolved the problem and this works as expected. Thank you for quick response.

@Michal if you specifyed a path like c:\dir1\dirs2 and if dir1 does not exist it will fail (The specified path was not found)
