'FileNotFoundError' occurs when trying to access a file that does not exist. Verify the file path, check for typos, and ensure that the file is in the correct directory.

'FileNotFoundError' is a specific exception raised in Python when an attempt is made to access a file that does not exist in the specified location. This can happen for several reasons, including incorrect file paths, typographical errors in the file name, or the file simply not being present in the expected directory. To resolve a FileNotFoundError, start by carefully reviewing the file path you provided. Ensure that the path is accurate and correctly formatted, especially if you're using relative paths. Consider using absolute paths for clarity. Double-check the spelling of the file name, including the file extension, as even a minor typo can lead to this error. If you're working with user-supplied file paths, implement error handling to catch the FileNotFoundError and provide user-friendly feedback, possibly prompting the user to check their input. By following these guidelines, you can effectively handle FileNotFoundErrors in your Python applications.
