Question

Write a Python function that takes as input parameters base_cost (a float) and customer_type and prints a message with information about the total amount owed and how much the tip was.

As a reminder, the tip amounts are 10%, 15% and 20% for stingy, regular, and generous customers. And the tax amount should be 7%.

The total amount is calculated as the sum of two amounts:

1. check_amount = base_cost*1.07
2. tip_amount = tip_percentage*check_amount

To receive full credit, you must use string formatting to print out the result from your function, and your amounts owed should display only 2 decimal places (as in the examples below). To "pretty print" the float to a desired precision, you will need to use this format operator (refer back to class slides for more explanation): %.2f

Print the results to the console like in the example below, including the base cost of the meal, tax, three tip levels, and total for regular customers.

Test cases:

• inputs: check_amount = 20, customer_type = "regular" --> output: Total owed by regular customer = $24.61 (with $3.21 tip)
• inputs: check_amount = 26.99, customer_type = "generous" --> output: Total owed by generous customer = $34.66 (with $5.78 tip)
• inputs: check_amount = 26.99, customer_type = "generous" --> output: Total owed by stingy customer = $16.83 (with $1.53 tip)

#define function

#code to test / call function here

Answer 1

Thanks for the question, here is the code in python

The 3rd example given in question is incorrect

• inputs: check_amount = 26.99, customer_type = "generous" --> output: Total owed by stingy customer = $16.83 (with $1.53 tip)

the customer type in the above passed is generous but why the output is showing for stingy, I think this is incorrect

Here is the function, I have given explanatory names so that you can follow the code precisely and also used pretty formatting.

let me know for any questions or help.

thank you !

def print_tip(base_cost, customer_type):

    TAX_PERCENTAGE = 1.07
    STINGY_PERCENTAGE = 0.1
    REGULAR_PERCENTAGE = 0.15
    GENEROUS_PERCENTAGE = 0.20

    check_amount = base_cost * TAX_PERCENTAGE
    tip_amount = 0.0

    if customer_type == 'regular':
        tip_amount = check_amount * REGULAR_PERCENTAGE
    elif customer_type == 'generous':
        tip_amount = check_amount * GENEROUS_PERCENTAGE
    elif customer_type == 'stingy':
        tip_amount = base_cost * STINGY_PERCENTAGE

    total_amount = tip_amount + check_amount

    print('Total owed by {} customer = ${} (with ${} tip)'.format(customer_type, '%.2f' % total_amount,'%.2f' % tip_amount))


print_tip(20, 'regular')
print_tip(26.99, 'generous')
print_tip(14.99, 'stingy')
