Study Notes

Problem Solving Process

Consist of four steps: Analysis, Design, Implementation and Testing
Analysis defines requirements and specifications
Design develops an algorithm and forms a solution
Implementation carries out the design and implements the solution
Testing ensures the implementation meets requirements

Programming Languages

Programming Languages are used to instruct computers to perform tasks
Programming languages started with machine language, also known as machine code
Machine Language is a collection of binary digits, 0s and 1s, and the only language that can be directly executed
Assembly language was created to address the issues of machine language and requires an assembler to translate code
High-level languages, like Python, are easier to write and understand and need a compiler or interpreter to translate them to machine code
Compiled languages are translated into machine code before execution
Interpreted languages are translated line by line until completion or an error occurs
Static typing languages require type specification when creating a variable
Dynamic typing languages do not require type specification

Programming Paradigms

Programming paradigm is a way of organizing code within an application
Procedural Programming divides a program into a set of procedures (routines or sub-routines)
Object-Oriented Programming (OOP) divides a program into objects, which are constructed to form a solution
OOP bundles methods (procedures) and data to form objects

Benefits of Using Functions

Maintainability
Reusability
Simplicity
Cleaner variable namespace
Easier debugging

Characteristics of Python Language

Python is an interpreted language
Python is a dynamic language
Python is case-sensitive
Python requires assignment of a value to create a variable

Indentation in Python

Indentation, the whitespace at the beginning of a line of code, determines the scope of a statement
Consistent indentation is required for statements within the same scope.
Indentation is essential for Python program logic

Boolean Expressions

Boolean expressions evaluate to either True or False
There are six relational operators: >, <, >=, <=, ==, !=
