Question

Can you write this program, but in python, I just wanna see what am I doing wrong. thank you

Instructions: The Gas-N-Clean Service Station sells gasoline and has a car wash. Fees for the car wash are $1.25 with a gasoline purchase of $10.00 or more and $3.00 otherwise. Three kinds of gasoline are available: regular at $2.89, plus at $3.09, and super at $3.39 per gallon.

User Request: Write a program that prints a statement for a customer.

Analysis: Input consists of number of gallons purchased (R, P, S, or N for no purchase), and car wash desired (Y or N). Gasoline price should be program defined constant. Sample output for these data is

Enter number of gallons and press <Enter> 9.7

Enter gas type (R, P, S, or N) and press <Enter> R

Enter Y or N for car wash and press Y

Answer 1

#Python program that prompts for number of gallons , gas type and Y or N for car wash then print the #total due for car.
#gas.py

def main():
    #gas type costs
    REGULAR=2.89
    PLUS=3.09
    SUPER=3.39

    carWashCost=0
    pricePerGallon=0

    gasOlineCost=0

    # number of gallons from keyboard
    numGallons=float(input('Enter number of gallons and press : '))

    #read gas type
    gasType=input('Enter gas type(R, P, S or N) and press : ')

    #read Y or N for car wash
    carWash=input('Enter Y or N for car wash and press : ')

    #check gasType and corresponding price per gallon
    if gasType=='R':
        pricePerGallon=REGULAR
    elif  gasType=='P':
        pricePerGallon=PLUS
    elif gasType == 'S':
        pricePerGallon = SUPER
    elif gasType == 'N':
        pricePerGallon = 0


    #check if number of gallons is 10 or more then set car wash cost 1.25
    #otherwise less than 10, set car wash cost 3.00
    if numGallons >=10:
        carWashCost=1.25
    else:
        carWashCost=3.00

    #calculate teh gasoline cost
    gasOlineCost=numGallons*pricePerGallon

    print('************************************** * *')
    print('* Gas-N-Clean Service Station *')
    print('* March 2, 2004 *')
    print('************************************** * *')

    #calculate total due by adding gasonline cost to car wash cost
    totaldue=gasOlineCost+carWashCost


    #print the valus on python console with two decimal values
    #{0} for first argument in format
    #{0:.2f} is for print value upto two decimal values  where f is for float values
    print('Amount Gasoline purchases {0} Gallons'.format(numGallons))
    print('Price pre gallons $ {0}'.format(pricePerGallon))
    print('Total gasoline cost $ {0:.2f}'.format(gasOlineCost))
    print('Car wash cost $ {0:.2f}'.format(carWashCost))
    print('Total due ${0:.2f}'.format(totaldue))
    print('Thank you for stopping')
    print('Please come again')
    print('Remember to buckle up and drive safely')
main()

Sample Output:

Enter number of gallons and press : 9.7
Enter gas type(R, P, S or N) and press : R
Enter Y or N for car wash and press : N
