The range command produces a series of numbers, and tries to assign them
to the variable following the keyword 'for'. It has to be a variable,
because you can't assign something to anything that can't change --
like 1. 1 will always be 1, and you can never change it, and neither can
'range'. Now if you use _i_ instead of _1_, you'll have created a variable
that can take any value, including the numbers 0 to 9.
