SalesTax.py

# In many areas, different goods are taxed at different rates.
# Areas may charge higher tax rates for items like alcohol,
# gasoline, and soda, and lower tax rates for items like
# grocery items, medicines, and clothes.
#
# Write a class called PurchasedGood. The constructor for
# PurchasedGood should have one positional parameter called
# price, which is the price of the good as a float. It should
# then have two keyword parameters in this order:
# - category, which is the category the good falls into.
#   category should have a default value of "General".
# - tax, which is the sales tax rate. tax should have a
#   default value of 0.07.
#
# These three values should be stored in attributes called
# 'price', 'category', and 'tax'.
#
# Then, add a method called calculate_total. calculate_total
# should calculate the price plus the price times the tax
# rate, then round the result to 2 decimal places and return
# the result. Remember, you can round to two decimal places
# using round(total, 2).


# Add your class here!

class PurchasedGood:
    def __init__(self, price, category="General", tax=0.07):
        self.price = price
        self.category = category
        self.tax = tax

    def calculate_total(self):
        new_price = self.price + (self.price * self.tax)
        return round(new_price, 2)

# You can change these lines to test your code in different
# ways.

# If your code works correctly, this will originally run
# error-free and print ignoring rounding errors):
