ex2: pep8: Inline comments should be separated by at least two spaces from the statement

[todd-dsm]

In Exercise 2, pep8 suggests the inline-comment should have 2 spaces between the statement and the octothorpe.

A very small but, apparently, important distinction according to the pep. It's worth noting that even with 1 space the program works as described.

Cool, sort of a weird requirement but I'll change it.
