title: Rename column in Pandas Python not working
body: <p>I'm trying to rename one column with the <code>rename</code> function. However, nothing changes. Could someone help me? </p>
  
  <p>The code i have tried is the following:</p>
  
  <pre><code>Snd_Mer_Vol_Output = Snd_Mer_Vol_Output.rename(columns={'(1,Snd_Mer_Vol_Probability')': 'Snd_Mer_Vol_Probability'})
  
  
  File "&lt;ipython-input-28-057b6859dfa6&gt;", line 1
  Snd_Mer_Vol_Output = Snd_Mer_Vol_Output.rename(columns={'(1, 'Snd_Mer_Vol_Probability')': 'Snd_Mer_Vol_Probability'})
                                                                                          ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>Thank you.</p>
