2.2.2. Software Sales

A software company sells a package that retails for \(\$880\). Quantity discounts are given according to the following tables:

Table 2.3 Discount Table

Quantity	Discount
\(4\)-\(39\)	\(10\%\)
\(40\)\(-199\)	\(15\%\)
\(200\)-\(999\)	\(30\%\)
\(1000\)-more	\(42\%\)

Write a Python program that asks the user to enter the number of packages purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount.

Sample Output

Use the values in Table 2.4 below to test your program.

Table 2.4 Test Cases

Case	quantity
1	-3
2	3
3	4
4	42
5	202
6	9001

Ensure your program’s output matches the provided samples exactly. This includes all characters, white space, and punctuation. In the samples, user input is highlighted like this for clarity, but your program should not highlight user input in this way.

Case 1 Sample Output

$ python3 software_sales_login.py How many packages will be purchased: -3 Invalid Input!

Case 2 Sample Output

$ python3 software_sales_login.py How many packages will be purchased: 3 No discount applied. The total price to purchase 3 packages is $2,640.00.

Case 3 Sample Output

$ python3 software_sales_login.py How many packages will be purchased: 4 10% discount applied. The total price to purchase 4 packages is $3,168.00.

Case 4 Sample Output

$ python3 software_sales_login.py How many packages will be purchased: 42 15% discount applied. The total price to purchase 42 packages is $31,416.00.

Case 5 Sample Output

$ python3 software_sales_login.py How many packages will be purchased: 202 30% discount applied. The total price to purchase 202 packages is $124,432.00.

Case 6 Sample Output

$ python3 software_sales_login.py How many packages will be purchased: 9001 42% discount applied. The total price to purchase 9001 packages is $4,594,110.40.
