Write a Python function that takes as input parameters base_cost (a float) and customer_type and prints a message with informati
PSYCHO15rus [73]

Answer:

Explanation:

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.

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')
