Is there a way to make a list element and and a variable always
show the same value, even if that value is a simple number or string ?
Eg
   >>> a = [100,200]
   >>> weight  = a[0]
   >>> length  = a[1]
   >>> length  = 222
   >>> a
       [100, 222]
and vice versa:
   >>> a[0]    =  99
   >>> weight
   >>> a
       [99, 222]
