title: Remapping dataframe values with dictionary key/value
body: <p>I have a dictionary of simulated team scores:</p>
  <pre><code>{'t1': 83,
   't2': 82,
   't3': 66,
   't4': 74}
  </code></pre>
  <p>And a dataframe of matchups:</p>
  <pre><code>team_home  score_home  team_away  score_away
  t1         0           t2         0
  t3         0           t4         0
  </code></pre>
  <p>I want to remap the scores in the dataframe with the corresponding team's score in the dictionary. The final output should look like this:</p>
  <pre><code>team_home  score_home  team_away  score_away
  t1         83           t2        82
  t3         66           t4        74
  </code></pre>
