'Extracting unique values from multiple rows in csv file

I have real estate data csv file. There's a lot of information in rows, which is repeating, like in example below:

Row1:
Su baldais, Skalbimo mašina, **Viryklė**, **Indaplovė**, Vonia
Row2
Virtuvės komplektas, **Viryklė**, **Indaplovė**, Dušo kabina, Rekuperacinė sistema

As you can see, there is a lot of data, which is repeating (i marked it with stars). Is there a way to get only unique values from all the rows with python ?
