PYTHON PROGRAMMING Week 5 - Tuesday

THE FRIENDSHIP ALGORITHM Note the infinite loop!

LAST WEEK Conditionals and control flow

REMINDERS Key Terms & Concepts – weeks 1 & 2 Print out programs and annotate them

TODAY Algorithms  What is an algorithm?  How to write a simnple algorithm Python  Writing functions with and without parameters  How to call functions  Some library/built in functions

SIMPLE FUNCTION What does it do? Note  We can call it from IDLE  We can call it from another program  There is an existing functions that does this – max()  We can easily set up our own libraries of functions

ALGORITHM DESIGN Making a sandwich

ALGORTHM DESIGN Making Tea

PRACTICAL Codecademy:  Conditionals and Control Flow Plus  Exercises  Challenges

RECAP What is an algorithm? What is a function? A parameter? How can functions help us write complex programs?

TOMORROW More on algorithms  approaches to writing them  why functions are our friends Functions – practice Mastery Task 2

HOMEWORK Tomorrow!
