title: Remove double and single square brackets from text file generated from python
body: <p>I have this text file which was generated from python. <a href="https://www.dropbox.com/s/xgn7s3skdxd78x5/ddn140_Stmax.txt?dl=0" rel="nofollow">Text File</a>. I noticed that the data contained in two of the columns are enclosed withing double and single brackets respectively. These two column values were saved as string as were the other columns. </p>
  
  <p>How can I remove these brackets when I import the text file into python.</p>
  
  <p>Thank you,</p>
