Lecture 2 - Programs and Programming

• Almost all languages have input, output, math, conditional execution (decisions), and repetition (loops)
• Seven steps of programming The Seven Steps Poster
  • Watch video on Developing an Algorithm
  • Watch video on A Seven Step Approach to Solving Programming Problems
• Consider how to decide if a number is a prime number
• To play with Python:
  • Install it on your machine or a public machine: Download
• Quick tour of Python
  • Editing window, variable explorer, and console
  • Main numerical types: whole numbers (int) and numbers with decimals (float)
  • + - * // (rounded division) and % (remainder / modula) produce in if both sides are an int, float if either or both are floats
  • / (regular division) and // (rounded division) produces float with ints or floats
  • ** to do powers
  • Python doesn't know everything to start with; may need to import things
    • import MODULE means using MODULE.function() to run
    • import MODULE as NAME means using NAME.function() to run
  • VAR = input("prompt: ") will ask the user for a value and stores whatever they type as a string
  • NUM = int(VAR) will convert the item in VAR to an integer if it looks like an integer; error otherwise
