Assignment

• Write a Python program that prompts the user for the number of entries on a receipt, and then for each entry, then prompts the user for the price of those items -- output the unit price of each item.
• After all of the entries have been entered, prompt the user to enter the sales tax.
• Calculate the average price per item, and output whether store should be considered typical, expensive, or cheap.
• See the sample transcript below. You can assume that all user inputs will be valid when we test the program. Your solution should match the output format exactly.

Grading - 100 points

• 35 points - The Average Cost Per Item calculation is correct.
• 15 points - The user is prompted to enter the number of entries from the receipt (5 points), the price of each entry (5 points) and the quantity of items on each entry (5 points).
• 10 points - With the exception of the actual average cost per item, the output format matches the output format of the transcript exactly (2 points for each type of difference up to 10 points).
• 5 points - The average cost per item is displayed with two digits to the right of the decimal.
• 10 points - A function named get_rating is defined that takes three float parameters (item, lo, hi) and correctly returns a rating as a string (e.g. "cheap", "expensive", or "typical").
• 10 points - A function named main is defined (5 points). The only python statement that does not appear in this function or the translate function is the call to the main function, e.g. main() (5 points).
• 10 points - The Python solution is easy to understand and does not contain unnecessary code (2 points for each type of improvement up to 10 points).
• 5 points - An appropriate Python comment appears at the top of the submission. See below for the type of information that should appear.

Sample Transcripts

How many entries are listed on the receipt? 1 Enter number of items in entry 1: 2 Enter that entry's total cost: 8 Cost per item of entry 1 is: 4.0 Enter sales tax (%): 4 total cost (with tax): 8.32 total number of items: 2 average cost per item is 4.16 That store seems typical

How many entries are listed on the receipt? 3 Enter number of items in entry 1: 4 Enter that entry's total cost: 12.84 Cost per item of entry 1 is: 3.21 Enter number of items in entry 2: 16 Enter that entry's total cost: 68.48 Cost per item of entry 2 is: 4.28 Enter number of items in entry 3: 2 Enter that entry's total cost: 44.50 Cost per item of entry 3 is: 22.25 Enter sales tax (%): 5.5 total cost (with tax): 132.7401 total number of items: 22 average cost per item is 6.03 That store seems expensive
