title: How to get a line in a text through user's input?
body: <p>I have a problem with a text file which contains a list of 55 random numbers (all in one column). What I'm trying to do is to ask the user to choose a line number so that I can bring it up but I dont know what to put in the code for this.</p>
  
  <p>I'm trying to do a little game, the whole point is to ask the user to choose a line and then make him/her guess what number is hidden on that line.</p>
  
  <p>Any advice would be really helpful. Thanks</p>
