the solution you're creating is *slightly* different than the original
spec in the problem (Exercise 13-3). the argument to dollarize() is
supposed to be a *float*, not a string. other than that, you're well
on your way!
also, be aware of the typo in the class skeleton provided on p. 619.
the published changed the "`"s to "'"s on line 13. since the backtick
quotes are going away in Python 3, i would just suggest changing
"return `self.value`" to "return repr(self.value)".
aside from this, the way i usually solve this problem is to save off
the sign, round off the fraction/pennies, and then break it up into
dollars and cents, then process the commas into the dollar amount, and
finally merge everything back together with the sign and the $.
best of luck!

ps. marty's use of locale is a great add-on to this problem. i've had
some students go this distance and implement it in a similar way but
not very often.
