title: why does csv remove the 0's in the begining if the number is too big ? how do you fix this?
body: <p>For example if i have a column of numbers (large numbers) like 0036812321991 , it shows something like 3.68e+10</p>
  
  <p>If there is a 0 in the beginning , csv removes it and i need the number as it is , no  modification whatsoever . 
  I need to retain the number as is </p>
  
  <p>I tried using pandas and convert it into the string using "astype(str)" but it still removes the 0 </p>
  
  <p>Any help would be helpful </p>
