These two lines

for r in var:
     helper = var[r].get()

are being redundant.

The loop returns elements from the list (one-by-one).   Also  var[r] 
attempts to return an element from the list (indexed by r -- expected to 
be an integer).

Either of these remove the redundancy (but the first is more Pythonic)

   for r in var:
       helper = r.get()

or

   for i in range(len(var)):
      helper = var[i].get()
