*= operator

This is a piece of code that calculates tax and tip : def tax(bill): """Adds 8% tax to a restaurant bill.""" bill *= 1.08 print "With tax: %f" % bill return bill def tip(bill): """Adds 15% tip to a restaurant bill.""" bill *= 1.15 print "With tip: %f" % bill

print("%.2f" % total)

meal = 44.50 tax = 0.0675 tip = 0.15 meal = meal + meal * tax total = meal + meal * tip print("%.2f" % total) What do the lines inside the parentheses in this statement print("%.2f" % total) mean ? What does "%.2f" % total represent ? Thanks alot ... Gengyang --
