Hello! This is actually my first time posting on a forum, ever haha. Well I'm going through a book on python, thought I understood naming variables, but found that I don't know how to fix NameError: name 'tip_15' is not defined
# Tip Buddy # Have User enter bill amount # output tip amount and # bill total # Patrick Crowley # 8/7/2017 # gather information from user bill = float (input ("Please enter amount shown on bill.")) # output tip amount by 15% and 20% tip20 = bill * 0.2 tip15 = bill * 0.15 # 15% print ("\n\nIf your service was satisfactory today,", \ tip_15 , "is a resonable tip Based on 15%") print ("Your total would be:", bill + tip_15) #20
