Study Notes

Problem-Solving Steps in Computational Thinking and Programming

  • Identify the problem: define the problem and its constraints
  • Design: develop a plan or algorithm to solve the problem
  • Implement: translate the design into a programming language
  • Test: verify the correctness of the solution
  • Evaluate: assess the effectiveness and efficiency of the solution

Data Types in Python

  • Mutable data types: Lists, Dictionaries, Sets
  • Python data type mutability: values can be modified after creation

Purpose of Flowcharts

  • Visual representation of algorithms and programs
  • Simplify complex problems and programs
  • Identify logical flow and control structures
  • Aid in problem-solving and program design

Execution Modes in Python

  • Script mode: writing and executing code in a single session
  • Program mode: writing and saving code in a file before execution
  • Program mode advantage: code can be reused and edited

Operators in Python

  • in operator: test if a value is present in a certain data type (e.g. lists, strings, dictionaries)
