Variables in Python are names. They aren't the cubbyholes into which you put values, they are sticky notes on the front of the cubby hole. Parameter passing in Python always work the same way - you create a new name pointing to the passed object. Fin. The confusion you're having isn...

This implementation stems naturally from the Python array representation. The first parameter variable in exchange() is a reference to the array, not to all of the array’s elements: when you pass an array as an argument to a function, you are giving it the opportunity to operate on that ...
