The mode that is NOT one of the four modes for opening a file in Python using the `open()` function is **"d" (delete)**.

The valid modes are:
- `"r"` for reading
- `"a"` for appending
- `"w"` for writing

There is no mode `"d"` for deleting files in the `open()` function. To delete a file, you would use the `os.remove()` function from the `os` module.
