python Tutorial for AI & ML | Part - 1 | Strings
Welcome to Part 1 of our Python for Artificial Intelligence & Machine Learning tutorial series! 🚀
In this beginner-friendly guide, we dive deep into one of the most foundational data types in Python: Strings. Whether you are starting your journey into artificial intelligence, data science, or simply learning to code, mastering strings is essential for processing text data.
This step-by-step tutorial covers how to create, manipulate, and format strings.
🔍 What You’ll Learn in This Video:
Introduction to Strings & Variables: Learn how to declare strings using single vs. double quotes, and store them inside variables.
Working with the print() & len() Functions: Discover how to output your strings to the console and calculate string length.
String Indexing & Slicing: Access specific single characters or extract substrings using index value (including negative indexing to read strings backward).
Essential String Methods: Learn various string methods like .lower(), .upper(), .title(), .capitalize(), .count(), .find(), and trimming whitespace with .strip().
String Concatenation & F-Strings: Join strings using operators and leverage modern Python F-strings to dynamically embed variables and format text cleanly.
