IsADirectoryError: Path is a Directory

IsADirectoryError: [Errno 21] Is a directory: '/tmp/data'

Quick Answer

You are trying to open a directory as a file. Check your path to make sure it includes the filename, not just the directory.

Why This Happens

The open() function expects a file path, not a directory. This error occurs when your path variable contains a directory instead of a file.

The Problem

with open('/tmp/data') as f:
    content = f.read()

The Fix

with open('/tmp/data/config.json') as f:
    content = f.read()

Step-by-Step Fix

  1. 1

    Check the path

    Verify with Path(path).is_file().

  2. 2

    Add the filename

    Append the filename: Path(dir_path) / 'file.ext'.

  3. 3

    List directory contents

    Use os.listdir(path) to see files in the directory.
