title: Pandas - contains from other DF
body: <p>I have 2 dataframes:</p>
  <p>DF A:</p>
  <p><a href="https://i.stack.imgur.com/Qpqf0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Qpqf0.png" alt="enter image description here" /></a></p>
  <p>and DF B:</p>
  <p><a href="https://i.stack.imgur.com/dImkp.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dImkp.png" alt="enter image description here" /></a></p>
  <p>I need to check every row in the DFA['item'] if it contains some of the values in the DFB['original'] and if it does, then add new column in DFA['my'] that would correspond to the value in DFB['my'].</p>
  <p>So here is the result I need:</p>

  <p>I tought of converting the DFB['original'] into list and then use regex, but this way I wont get the matching result from column 'my'.</p>
