FileNotFoundError from os.walk()

• path
• FileNotFoundError
• open
• os.walk

os.walk() generates a 3-tuple of directory, files, and subdirectories. Many beginners attempt to access entries from the latter two directly, but they are relative to directory, so you have to add that back on, like open(os.path.join(directory, entry))

• using os.remove() in os.walk() for loop returns FileNotFoundError
