除了文件和目录还有别的吗？

Question

I'm working on a project that iterates through directories and looks for files in windows.

for element in os.listdir(path):
    new_path = os.path.join(path, element)
    if os.path.isdir(new_path):
         pass
    elif os.path.isfile(new_path):
         pass
    else:
         pass

Now what I'm curious about, is if windows or any other operating system has any other tree elements? If not is it still a good idea to check for that edge case?

Answer 1

Checking path module documentation I see that there are multiple predicates:

1. isfile()
2. isdir()
3. islink()

However when islink() is true , one of isdir() and isfile() is true too (since both of those follows symbolic links).

You have to be careful, that when there is no file or directory at path, both are false . You can verify that using exists() . However in your example paths point to existing items, since you get them from listdir() .
