    9. Repeat Steps #6-8 several times
    10. Set breakpoints and run the debugger (only after you have read every one of your lines over and over again)
  • Lab 13: Harvest the Field
  • Lab 14: Clear the Path

      • Example: Whenever you need to "remember" or keep track of some information
    2. Defining and calling a function
    3. Using an if statement

  • While Loop practice
    1. Write a loop that prints 0 to 10
    2. Write a loop that prints 10 to 0
    3. Write a loop that prints from 19 to 77
    4. Write a loop that prints the first 50 even numbers
    5. Prompt a user for a number N. Write a loop that then prints out the first N even numbers (Hint: Use multiple variables)

Wednesday - Friday (10/14/15 - 10/16/15)

Agenda:

  • APS PRIME Internship Program - see Ms. Burgos for more information

  • Introducing the Debugger
    1. Load your Lab3.py code
    2. Set a debug breakpoint at the line where the world is created (clicking on the left gray gutter will leave a red dot)
    3. Hit the debug button (ladybug)
    4. What happens? The code should execute, but stop at the debug breakpoint
    5. You may now use the debug stepping buttons:
      1. Step-into (arrow into box) - executes current line and steps into any function calls
      2. Step-over (arrow over box) - executes current line and goes to next one (does *not* enter function calls)
      3. Step-out of (arrow out of box) - steps out of the current function call
  • Lab 10: Lab 2 Redo
  • Lab 11: Maze Solver

Warmup:

  • Think about the following questions (you may discuss with a partner):
    1. What is the purpose of a password for a login (authentication) system?
    2. Why do password systems require a minimum password length (e.g. 8 characters or more)?
    3. Why do password systems require the use of both upper and lowercase characters as well as special characters (e.g. !@#$%^&*)?
