IsADirectoryError: Path is a 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.
