title: Matching 2 almost same dataframes to be equal
body: <p>I have a df1 like this:</p>
  
  <pre><code>text 1
  text 2
  text 3
  text 4
  text 5
  </code></pre>
  
  <p>And another one df2 like this:</p>
  
  <pre><code>text 1
  text 2
  text 3
  text 5
  </code></pre>
  
  <p>The problem is my dfs are almost the same, they have many rows and I can find the one that is additional to the first df in order to know who is it?</p>
  
  <p>Is there any possible option to compare the two dfs and find the one row it is the difference between them?</p>
