Python

1. A programming language

2. Algorithms are simple steps to instruct the program.

3. Decomposition

   • Breaking down a program into smaller steps.

4. Programming

   • Sequencing instructions
     • One after the other
   • Accuracy is important
   • Sequence order is important.

5. Python's development environment

   • IDLE
     • Integrated Development Environment
       • Interactive Mode - seeing your results as you type, using the Shell Window
       • Script mode - saving the program and running it later, using the Editor Window

6. Variables

   • A location in memory where you can temporarily store data

   • Using a variable

7. Who is it used by?

   • NASA
   • Dropbox
   • Paint Shop Pro
   • Google's Search Engine
   • Civilisation 4 Computer Game
   • CERN Large Hadron Collider Research

8. print ("Hi Mister Penguin!") Press Enter, resulting in... Hi Mister Penguin!

9. Syntax errors

   • When you type the programming code wrong, it is a snytax error.

10. Computer Bugs

    • Error in the program
      • De-bugging
        • The way we solve the problem in the code, taking the error out if the code.
