Hayden Walker 2019 This is a portfolio of some of my favourite programs that I wrote during the summer of 2019. *The programs are arranged alphabetically (By folder name, not by title) NOTE: The following dependencies are required in order to successfully run some of these programs. These dependencies are *not* included in the Python Standard Library. *Matplotlib plotting library (for the Collatz Conjecture program) *Pygame (for the aquarium program as well as Conway's Game of Life) ------------------------------------------------------------------------------------------------------------ Title (Date) *Skills Desc. ------------------------------------------------------------------------------------------------------------ Aquarium (19 August) [Requires Pygame] *Pygame *Importing sprites *Random library *Object-oriented programming *Multiple instances of a class *Each instance is unique and randomized *Game loop *Math operators *Multiplication *Conditionals *Functions *Methods A simple aquarium. A random number of fish are spawned, each being an instance of the Fish class. Each is randomly assigned one of four breeds, and each has a randomly assigned speed. The fish will change directions when they come in contact with the screen's edge. Furthermore, each 50 millisecond cycle, each fish has a 1% chance (for each axis) of changing direction on its own, regardless of its position. ------------------------------------------------------------------------------------------------------------ Binary to Decimal Converter (18 August) *String slicing *Reversing *Concatenation *Iterables *Conditionals *Math operators *Powers A simple binary to decimal converter; will accept an arbitrtary amount of bytes of arbitrary lengths. ------------------------------------------------------------------------------------------------------------ Caesar Cypher (25 July) *Iterables *Conditionals *For Loops *List wrapping *Functions Takes an encryption key (n) from 0-25 and moves each character ahead n spaces in the alphabet. If the letter reaches z, it wraps back to a. ------------------------------------------------------------------------------------------------------------ Cash register (3 August) *Rounding *While Loops *Conditionals *Functions Takes a sales total and amount tendered, then calculates change and lists the amount of each denomination of change to return. ------------------------------------------------------------------------------------------------------------ Collatz Conjecture (7 August) [Requires Matplotlib] *A Classic Algorithm *While Loops *Conditionals *Math operators *Modulus *Floor division *Addition *Matplotlib Graphing Library Takes a positive integer (n), and depending on its parity, will either divide it by 2 or multiply it by 3 then add 1, and repeat the whole process until the integer is equal to 1. It will then display a graph where x is the number of steps and y is the value of n. ------------------------------------------------------------------------------------------------------------ Conway's Game of Life (22 August) [Requires Pygame] *A Cellular Automaton *Random Library *PyGame *Rectangles *Conditionals *Iteration *Object-Oriented Programming *Functions *Methods *Game Loop Generates 100 squares that can each be either living or dead; each 1-second "generation," if a living square has less than two or more than three living neighbours, it will die from either underpopulation or crowding. If a dead square has exactly three living neighbours, it will become living, via reproduction. ------------------------------------------------------------------------------------------------------------ Line/square drawing (27 July) *Tkinter GUI Library *Canvas *Buttons *Inputs *Random library *Object-Oriented Programming *For Loops *Functions *Methods A GUI application that takes a number (n) and, depending on which button is pressed, will generate either n lines or n rectangles, all of random size, position, and colour. It will display the last action completed in a status bar at the bottom. ------------------------------------------------------------------------------------------------------------ Hangman (5 August) *Random Library *Reading from a text file *For Loops *Game Loop *Conditionals *Iterables *Functions A game of hangman that pulls words from a 100-word text file. ------------------------------------------------------------------------------------------------------------ Minefield/Minesweeper (20 July) *System commands *Random Library *Wrapping *Iterables *Conditionals *Functions *Game loop A game that draws a 5x5 grid, in which a random number of randomly placed mines are hidden. Goal: Clear the board without hitting a mine. ------------------------------------------------------------------------------------------------------------ Pig Latin (19 July) *String slicing *String concatenation *Conditionals Converts a word into "Pig Latin;" i.e. if the word begins with a vowel, it will add "ay" to the end, and if it begins with a consonant, it will move the first letter to the end of the word and then add "ay." ------------------------------------------------------------------------------------------------------------ Recursive Guessing Game (24 August) *Recursion *Conditionals *Math operators *Floor division *Addition The user chooses a number between 0 and 100 (unknown to the computer), and the computer will guess it. A light project that I included because of recursion. ------------------------------------------------------------------------------------------------------------ Monty Python's Python Soundboard (31 July) *Tkinter GUI Library *Buttons *Lambda Expressions *Object-Oriented Programming *Playing audio files A just-for-fun soundboard of clips from Monty Python's Life of Brian. Fun Fact: The Python Programming Language is named after Monty Python!
