CSC 221

Coursework for CSC 221 (Introduction to Programming in Python). Each mini project is a folder of standalone Python scripts. Every script is run directly from the command line and reads its input interactively from the keyboard.

Requirements

• Python 3.6 or newer (the scripts use f-strings)
• No third-party packages — standard library only (math, sys)

Running a program

python miniproject1/carpet_sale.py

Each program prints instructions describing what to type before it asks for input.

Mini Project 1 — input, calculations, and control flow

Console programs that read numeric input, apply formulas, and format currency output.

File	Description
painting_wall.py	Computes wall area, gallons of paint needed (350 sq ft per gallon, rounded up to whole cans), paint cost, 7% sales tax, and total.
pizza_party.py	For Friday, Saturday, and Sunday: computes pizzas needed (8 slices each, rounded up), cost, 7% tax, 20% delivery charge, and a weekend total.
carpet_sale.py	Processes 3 carpet orders. Carpet cost includes 20% extra for waste, labor is $0.75 per actual sq ft, 7% tax applies to both, plus a running total of all sales.
grade_calculator.py	Converts homework, quiz, midterm, and final points into percentages (capped at 100%), applies UG/G/DL weighting, and reports the course average and letter grade.
income_tax.py	Computes AGI, standard deduction by filing status, taxable income, federal tax from the bracket tables, and the amount due or refunded. Exits if AGI exceeds $120,000.

Input formats

• painting_wall.py — three prompts: wall height, wall width, cost per can.
• pizza_party.py — one line per night: people slices_per_person pizza_cost (e.g. 10 2.5 12.99).
• carpet_sale.py — one line per order: price_per_sqft width length (e.g. 12.50 10 15).
• grade_calculator.py — first line: UG, G, or DL. Second line: homework quizzes midterm final (e.g. 600.0 300.0 120.0 185.0).
• income_tax.py — one line of five whole numbers: wages interest unemployment status withheld, where status is 1 for single or 2 for married (e.g. 20000 23 500 1 400).

Mini Project 2 — lists, dictionaries, functions, and classes

Programs built around data structures and reusable functions.

File	Description
schedule_info.py	Looks up a course's room, instructor, and meeting time from three parallel dictionaries. Input is normalized to uppercase and invalid course numbers are reported.
finance.py	Prints a table of future investment values for years 1–20 using monthly compounding, via a futureInvestmentValue() function.
list_stats.py	Reads a list of whole numbers and reports minimum, maximum, mean, median, mode, and whether the list is a palindrome. Re-prompts on invalid or empty input.
contact_info.py	Stores contacts as a list of dictionaries and provides functions to print a full table, a phone-only table, look up a phone by full name, look up an address by first name, and list cities/states.
bank_account.py	Defines a BankAccount class with checking and savings balances, supporting deposits, withdrawals (rejected when they exceed the balance), transfers to savings, and a display method.

Input formats

• schedule_info.py — a course number such as CS101 (case-insensitive).
• finance.py — investment amount, then annual interest rate as a percent.
• list_stats.py — whole numbers on one line, separated by spaces (e.g. 1 2 3 2 1).
• contact_info.py — no input; runs a built-in test program against the sample contacts.
• bank_account.py — amount to withdraw from checking, then amount to withdraw from savings.
