100 Days of Code: An Introduction to Python

Course Overview

• Objective: Learn Python from zero to job-ready in 100 days
• Structure: Byte-sized lessons, complex projects, industry standard applications
• Engagement: Practice exercises, quizzes, and challenges
• Instructor Setup: Uses Replit, a browser-based collaborative IDE for ease of sharing code and following along

Python Programming Language

• History: Created by Guido van Rossum in 1991, inspired by Monty Python's Circus
• Type: Dynamically typed, object-oriented programming language
• Features: Simple, open-source, platform-independent, extensive library support
• Popularity: Wide usage in data science, machine learning, web applications, etc.

Getting Started

• Installation: Download Python from python.org based on your platform (Windows, Mac, Linux)
  • Important: Ensure you check the 'Add to PATH' option during installation on Windows
• IDEs: Can use VS Code, PyCharm, or Replit (preferred for course)

Using Replit

• Advantages: Easy to use, share code, follow along, manage projects even on slower computers
• Workflow:
  • Write code in main.py
  • Console output displayed on Replit servers
  • Video pane for simultaneous learning

Introduction to Programming

• Definition: Telling computers what to do using programming languages
• Analogy: Similar to human languages (e.g., English, Spanish), but for computers
• Examples: Python, C, C++, Java

What is Python?
