title: change input into int while its being placed into dictionary
body: <p>Is there any way to while reading into this dictionary to convert the values of each key value to int? Originally they are strings but i would prefer them to be ints. This is what i tried but i am getting errors! Each key looks like {'USA': ('123,123', '312,321,321')} But i want those numbers to be ints</p>
  
  <pre><code>**def _demo_fileopenbox():        
  msg  = "Pick A File!"
  msg2 = "Select a country to learn more about!"
  title = "Open files"
  default="*.py"
  f = fileopenbox(msg,title,default=default)
  writeln("You chose to open file: %s" % f)
  
  countries = {}
  
  with open(f,'r') as handle:
      reader = csv.reader(handle, delimiter = '\t')  
      for row in reader:
          countries[row[0]] = ((int(row[1])),(int(row[2])))
      while 1:
          reply = choicebox(msg=msg2, choices= list(countries.keys()) )
          writeln(reply + ";\tArea: " + (countries[reply])[0] + "\tPopulation: " + (countries[reply])[1] )
    **
  </code></pre>
  
  <p>thanks!</p>
