Python for Beginners – Basic Data Types in Python (int, float, str) | Lesson 6 (Free Full Course)
Welcome to Lesson 6 of the free “Python for Beginners” course! 🎉
In this lesson, we’ll learn about the most fundamental data types in Python: integers (int), floating-point numbers (float), and strings (str).
You’ll understand how Python stores information in memory, how variable types can change depending on the assigned value, and how to inspect data types using the type() function.
These concepts are essential for writing correct and meaningful Python code.
What you'll learn in this lesson:
✓ What a data type is and why it matters
✓ How Python represents integers (int)
✓ How floating-point numbers (float) work
✓ How to check the type of any value using type()
✓ How variables can change type when assigned new values
✓ The difference between 6 and 6.0
✓ What strings (str) are and how to define them
✓ How string concatenation works ("a" + "b")
✓ Why you can’t add a string to an integer (TypeError)
✓ How string multiplication works ("a" * 5)
✓ How data types affect the way Python evaluates expressions
