Code Efficiency

• Remove unnecessary code
  • Investigate loops and remove unnecessary code from within
  • Break out of a loop if task is complete
• Improve the speed of code
  • Choose the correct data structure
  • Use built-in functions when relevant (they have been highly optimised)
  • Explore different algorithm for the same task

Time Module

import time as t

t1 = t.time()
# Testing code here

t2 = t.time()
dt = t2 - t1
print(dt)

Programming Paradigms

• Each programming language can be classified based on its features described by a Programming Paradigm
• Each language can be classified into multiple paradigms

Machine Code & Assembly Language

Machine Code

The lowest-level paradigm that directly represents the instructions as a sequence of binary numbers

Assembly Language

Machine instructions by mnemonics and memory addresses by symbolic labels

Imperative Programming

• Imperative Programming is a programming paradigm that uses statements that change a program’s state
• Statements are executed in sequence
• Example features:
  • Direct assignment, common data structure, global variables
• Programming language that use imperative programming:
  • C, C++
  • Python
  • Java
