I have a dataframe with article texts. One row, among others, has several sentences with the copyright symbol, "©".

CEO Ethan Brown says the plant-based company is 'significantly reducing expenses' in an effort to focus on growth.

   tokens.remove(sentence)
   final = (".").join(tokens)
   df['summaries'].loc[(df['summaries'] == i)] = final
except:
 print("Yeah, we good.")

```
