Number guessing game

The number guessing game incorporates several simple but important elements of elementary programming and is a good candidate for an introductory programming example. If you’ve seen any programming course, you’ve probably seen the “Hello World” program. In Python it’s: print (“Hello World”)This is done to get the student(s) quickly to the point of having successfully installed…

A Quick Introduction to Python 3 Programming

hello world

This Quick Introduction to Python 3 aims to teach you just enough Python, so that you can get started in computer programming! First, you’ll want to install Python 3 or you can use the in-browser Trinket near the bottom of the page – just edit the code directly in there. If you have Python installed, you can…

Playing in Python with Pickover’s Premise per Pi

My favourite tweeter is Clifford A. Pickover. His tweets are delightful nuggets of math, physics & more. I have a copy of his fascinating The Physics Book. However, in these tweets, he claims that the string 44899 first occurs in pi at position 44899, counting from the first digit after the decimal point. I thought it might be…

Naive Mandelbrot Set

This is your basic Mandelbrot Set plotter. Very little effort made to speed it up, except for plotting top & bottom pixels together as they’re mirrored across the x-axis. Later I’ll show you some much faster programs! The heart of this program is the iteration of z2+c where c is a point in the complex…
