title: How to rename the first column of a pandas dataframe?
body: <p>I have come across this question many a times over internet however not many answers are there except for few of the likes of the following:</p>
  <p><a href="https://stackoverflow.com/questions/52386090/cannot-rename-the-first-column-in-pandas-dataframe">Cannot rename the first column in pandas DataFrame</a></p>
  <p>I approached the same using following:</p>
  <pre><code>df = df.rename(columns={df.columns[0]: 'Column1'})
  </code></pre>
  <p>Is there a better or cleaner way of doing the rename of the first column of a pandas dataframe? Or any specific column number?</p>
