Learning Outcome

At the end of this lesson, you will be able to:

• understand and use a list structure in a program

Review

• arrays

Lesson

• go over Lists, Chapter 5
  • Computer Based Problem Solving
  • "Lists"
• arrays are great, there is just one problem:
  • you have to know in advance how many elements will be in the array for when you declare it
  • not so good in programs like games, keeping track of the number of bullets fired!
• the above is try in most programming languages, but not Python
• in Python, arrays are really lists
• arrays (or lists) can shrink and grow as you need them

Activity

• null

Daily Assignment

• create a program that will accept marks (0 to 100) repeatedly from the user
  • use a textbox to accept a number and "Click" enter button
• place the values in a textView and also in a Python list
• when they click on the "average" button, it sends the list to a function that calculates average and returns it
• create:
  • GUI
  • flowchart - only for the function
  • Test cases
  • code
  • screenshots
  • GitHub link
• you MUST create the flowchart for the function before coding

Extra

• work on the weekly assignment

Homework!

• read over Arrays, Chapter 5
  • Computer Based Problem Solving
  • "2 Dimensional Arrays"
