[New-bugs-announce] [issue28299] DirEntry.is_dir() evaluates True for a file on Windows

[David Staab]

New submission from David Staab:

I'm using Python 3.5.2 on Windows 10 Pro to run the following code with the attached file structure.

The test code is:
from os import DirEntry, scandir

def test_is_dir():
    for item in os.scandir(TEST_DIR):
        if item.is_dir:
            print(item.path)
    return

TEST_DIR = '.'
test_is_dir()


The console output is:
===============
Connected to pydev debugger (build 162.1967.10)
.\20160707
.\scratchpad.py

Process finished with exit code 0
===============

I would expect to only see '.\20160707', but "if item.is_dir:" always evaluates to True.

I notice that changing the import line to "from os import DirEntry, scandir" yields the exception "ImportError: cannot import name 'DirEntry'".
