Variables, Data Types, and Operators

Variables, Data Types, and Operators

This lesson introduces the core building blocks of Python programming: variables, data types, and operators.

What you will learn

• How Python stores values in variables
• The built-in data types you will use throughout the course
• Operators for combining and comparing values

Why it matters

Python is the most widely used programming language in data science and software development. Every later topic in this course — NumPy, Pandas, APIs, scraping — builds directly on these constructs.
