Must be python Write a program that calculates and$$outputs$$a six month$$car insurance$$bill for$$a$$policy holder. $$ The$$insurance company has$$two types of$$policies: $$Premier$$and$$Select$.$If a driver has been with the insurance company $4$ or more years they are considered a$$Premier$$customer$,$otherwise they are considered a$$Select customer. $$ The policy cost$$varies depending$$upon$$the$$driver$$s age,$$risk level of the area the driver lives in $($high$$or$$low$$risk$)$and whether$$driver drives over $9000$ miles per year.$$Car insurance$$bills are computed$$as follows :$$Premier$$Bill$$: $$Driver$$s age over $24$High$-$Risk$9000$ or less$$miles$$ $$950$Over $9000$$$1100$Low$-$Risk$9000$ or less miles$$ $$880$ Over $9000$$$1000$Driver$$s age $24$ or under$$High$-$Risk$9000$ or less miles$$ $$1,185$ Over $9000$$$1,388$Low$-$Risk$9000$ or less miles$$ $$1,100$ Over $9000$$$1,200$Select$$Bill$$:$$Driver$$s age over $24$High$-$Risk$9000$ or less miles$$ $$1150$ Over $9000$$$1330$Low$-$Risk$9000$ or less miles$$ $$1080$ Over $9000$$$1225$Driver$$s age $24$ or under$$High$-$Risk$9000$ or less miles$$ $$1,390$ Over $9000$$$1,510$Low$-$Risk$9000$ or less miles$$ $$1,325$ Over $9000$$$1,400$The program should prompt the user to enter$$policy type$($P$$ for Premier or$$S$$for Select$),$ Driver$$s age, risk level $($H$$for High$$or$$L$$for Low$),$ a$$mileage$$level code$($Y$$for over $9000$or$$N$$for not over $9000).$Also$,$if any of the entered codes are not one of those specified, it should be treated as an errorFor$$select policies,$$the$$driver$$may$$have a AAA driver course certificate. $$If so$,$ there is a $5\%$ discount off the bill. Therefore, to calculate a$$select$$bill$,$ you must ask the user if the$$driver has a AAA.$$The output is formatted as :$$Premier$$Bill Amount : $$ $ $99999\mathrm{.}00$or$$Select$$Bill Amount : $$ $ $99999\mathrm{.}00$The program must contain$$two$$value returning functions :$$PremierBill$$:$$This function calculates and returns the billamount for a$$premier policy$$SelectBill$$:$$This function calculates and returns the bill$$amount for a$$select policy
