Lecture 2 - 8/27 - Programs and Programming

• Almost all languages have input, output, math, conditional execution (decisions), and repetition (loops)
• Seven steps of programming The Seven Steps Poster. Also, for Monday's class:
  • Watch video on Developing an Algorithm
  • Watch video on A Seven Step Approach to Solving Programming Problems
• Problem: Consider how to decide if a number is a prime number
  • Some "shortcuts" for specific factors but need to have a generalized approach
  • See if number is evenly divisible by any integer between 2 and the square root of the number - but how do we ask the computer to do that?
• Quick tour of Python
  • Console (with history tab), variable explorer (with other tabs), and editing window
  • Main numerical types: whole numbers (int) and numbers with decimals (float)
  • Can use % (called "mod") to get "remainder"
    • If both items are integers, result is an integer; if either is a float, result is a float
  • Relational operators: < <= == >= > !=
    • Result is is either True or False
• Comments in code:
  • If there is a #, Python ignores everything remaining in that line after the #
  • If there are """ or , Python ignores everything until the closing """ or
  • If you use # %% in Spyder, the editing window will set up a cell and light up the cell your cursor is in. Cells have no impact on how the code runs, just how the code appears in the window
