Introduction to Python

Overview

This module will set the foundation for Python programming, exploring Python’s history, its role in backend development, and the environment setup. Here’s an outline with details for each subtopic.

Subtopic 1: What is Python?

  • Description: A high-level, interpreted language known for its readability and versatility. Python supports various programming paradigms, including procedural, object-oriented, and functional programming.
  • Key Points:
    • Python’s syntax emphasizes readability and simplicity, making it accessible for beginners.
    • The language is used for web development, data science, AI, automation, and more.

Subtopic 2: History and Evolution of Python

  • Description: An overview of Python’s development since its inception.
  • Key Milestones:
    • 1989: Python was conceived by Guido van Rossum.
    • 1991: Initial release of Python.
    • 2000: Python 2 was released, adding features like list comprehensions and garbage collection.
    • 2008: Python 3 was introduced, which brought improvements but broke backward compatibility with Python 2.
  • Current Status: Python has a large ecosystem and community support, and it is frequently updated.

Subtopic 3: Why Choose Python for Backend Development?

  • Description: Analyzing Python's strengths in backend development and server-side applications.
  • Benefits for Backend Development:
    • Extensive Libraries and Frameworks: Flask and Django make backend development fast and efficient.
    • Readability and Maintenance: Python’s syntax and structure support clean, maintainable code.
    • Scalability: While not as fast as compiled languages, Python is highly scalable with the right frameworks and infrastructure.
    • Community Support and Integration: Python’s large community contributes to libraries for handling databases, APIs, and web servers.

Subtopic 4: Setting up Python Development Environment

  • Description: A guide to getting Python up and running on various platforms.
  • Steps:
    • Download Python: Visit python.org to download and install the latest version.
    • Environment Setup: Set up paths and environment variables for command-line use.
    • Choosing an IDE or Text Editor:
      • VS Code: Popular for extensions, debugging, and Git integration.
      • PyCharm: Comprehensive features for professional development.
      • Jupyter Notebook: Useful for data science, visualization, and learning purposes.
    • Setting up Virtual Environments: Use venv or virtualenv to create isolated environments for managing dependencies.
