I have a df where column 'elements' looks like this:
[![enter image description here](https://i.stack.imgur.com/13p35.png)](https://i.stack.imgur.com/13p35.png)

How can I split each word using this as separator "|" then send each word as key avoiding duplicates?
I used this but it's not working:

```
    for row in df.elements.itertuples():
       for l in row.elements.split("|"):
           list_elem.send_keys(l)

```
