Study Notes
Programming Languages
- Object-oriented languages use objects, which are self-contained units of data and code.
- Examples include Java, C++, and Python.
- Functional languages use functions, which produce values.
- Examples include Haskell, Lisp, and Scheme.
- Scripting languages are interpreted rather than compiled.
- Examples include JavaScript, Python, and Perl.
Programming Concepts
- Computer programming is the process of creating instructions for a computer to perform tasks or solve problems.
- These instructions are written in a programming language, which allows communication between humans and computers.
- The goal of programming is to create a series of logical steps that a computer can execute to achieve a desired outcome.
Key Concepts in Computer Programming
- Problem Solving: Translating real-world issues into solvable problems.
- Algorithms: Step-by-step procedures or sets of rules to solve specific problems.
- Programming Languages: Formal languages with syntax and semantics to communicate instructions to computers.
- Syntax and Semantics: Rules and structure of code (syntax) and the meaning behind the code (semantics).
- Data and Variables: Data is used by programming languages, and variables are used to store and manipulate data.
- Control Flow: Controlling the execution of instructions based on conditions.
- Functions and Modularization: Reusable blocks of code that perform specific tasks.
- Debugging: Identifying and fixing errors in code.
- Software Development Life Cycle: Planning, designing, implementing, testing, and maintaining software.
Algorithms
- Algorithms are essential for efficient problem solving in computer science.
- Algorithm Analysis: Evaluating the efficiency of an algorithm through time complexity and space complexity.
- Time Complexity: The amount of time an algorithm takes to execute based on the input size..
- Space Complexity: The amount of memory an algorithm uses based on the input size.
Common Algorithm Types
- Sorting Algorithms: Arrange elements in a specific order (e.g., Bubble Sort, Insertion Sort, Merge Sort, Quick Sort).
- Searching Algorithms: Locate a target element in a collection of data (e.g., Linear Search, Binary Search).
- Recursion: A technique where a function calls itself to solve a problem.
- Divide and Conquer: Breaking a problem into smaller subproblems and then recombining the solutions.
- Dynamic Programming: An optimization technique that breaks down problems into overlapping subproblems and stores the results to avoid redundant computations.
- Greedy Algorithms: Making locally optimal choices at each step to find a global optimum.
- Graph Algorithms: Dealing with data structures composed of nodes (vertices) and edges.
Optimization Algorithms
- Optimization algorithms aim to find the best solution from a set of possible solutions.
- Used in operations research, machine learning, and engineering.
Program Structure
- Data Structures: Organizing and storing data in a program (e.g., arrays, lists, dictionaries, linked lists).
- Error Handling: Managing unexpected events or errors during program execution.
- Input/Output (I/O): Interaction between the program and the user or external sources.
- Comments: Non-executable text that explains the purpose of the code.
- Constants: Variables with fixed values that cannot be changed.
- Utilities/Helper Functions: Functions or methods that provide additional functionalities.
Pseudocode
- What is Pseudocode: A way to represent code using natural language and programming language-like elements.
- Purpose: Not executable, used for representing algorithms, functions, and processes.
Installing Python
- Two ways to install Python on Windows:
- From the official Python website: Download the Windows installer and follow the instructions.
- From the Microsoft Store: Search for Python and click "Get" to install.
- Benefits of installing from the official Python website:
- Latest version of Python.
- Access to the full Python documentation.
- Ability to install third-party Python modules.
- Benefits of installing from the Microsoft Store:
- Easy to install and update.
- Integrated with Windows.
- Supported by Microsoft.
First Python Program
- The text describes creating a “Hello, World!” program in Python, highlighting the different modes of programming.
