Corrections to Chapter 8 (Advanced Programming)

[jack89roberts]

• 08_01_functional_programming: Function defined under this statement computes a sum not a mean:

  • We very often want to loop with some kind of accumulator (an intermediate result that we update), such as when finding a mean sum

• 08_01_functional_programming: Replace all instances of sys.float_info.min (smallest positive value) with -sys.float_info.max (most negative value).

• 08_01_functional_programming: The defined accumulate function has arguments in a different order than Python's reduce, which is introduced later. Would be clearer to use the same order as the built-in.
