Question

ULO 3: Describe and discuss the elements of effective programming style
ULO 4: Demonstrate an understanding of the software development life cycle and apply sound programming analysis techniques (design, coding, debugging, testing and documentation) to justify simple programming problems

In this project, you will work individually to write programs which demonstrate your understanding of IPO and usage of simple functions in Python programs.
Content and Structure:
You will have to write a modular program to:
1. Perform a series of transactions
2. This will be a project which students will choose and discuss with the lecturer prior to commencing.
3. Examples could be a scientific calculator, expense management system, online shopping system, banking system etc.
