title: I want to get rid of "-"(dash) in csv file(in Pandas)
body: <p>I have csv files and in the table, when there's no number, it has dash signs. </p>
  
  <p>All I know to solve it is to replace "-" with "" but it will affect "minus" signs. </p>
  
  <p>What should I do to remove dash signs when it's not actually minus signs followed by numbers?</p>
  
  <p>Thank you</p>
