title: Split a Pandas column of lists into multiple columns
body: <p>I have a Pandas DataFrame with one column:</p>
  <pre><code>import pandas as pd
  
  df = pd.DataFrame({&quot;teams&quot;: [[&quot;SF&quot;, &quot;NYG&quot;] for _ in range(7)]})
  
         teams
  0  [SF, NYG]
  1  [SF, NYG]
  2  [SF, NYG]
  3  [SF, NYG]
  4  [SF, NYG]
  5  [SF, NYG]
  6  [SF, NYG]
  </code></pre>
  <p>How can split this column of lists into two columns?</p>
  <p>Desired result:</p>
  <pre><code>  team1 team2
  0    SF   NYG
  1    SF   NYG
  2    SF   NYG
  3    SF   NYG
  4    SF   NYG
