title: Remove leading zeros when reading a csv file
body: <p>I have a CSV file that looks something like this -</p>
  
  <pre><code>    Location ID      Location Name
          3543459      A
           20541       B
            C320       C
             ...       ..
  </code></pre>
  
  <p>When I read the file using <code>pd.read_csv</code>, I get something like this - </p>
  
  <pre><code>Location ID      Location Name
     03543459      A
     0020541       B
     000C320       C
         ...       ..
  </code></pre>
  
  <p>How to avoid leading zeros? I did some research, all the questions I could ifind were based on producing the leading zeros in the df. </p>
