Week 3: Data Types

Learning Objectives

By the end of this week, students will be able to:

• Distinguish among integers, floats, strings, and booleans
• Convert values from one type to another when appropriate
• Predict how Python behaves when types are mixed in an expression
• Use string operations to inspect and build text values

Perspectival Reading

Reading: TBD

Reflection Questions

1. Why does it matter that the same characters can mean different things depending on their data type?
2. When should a number be stored as text instead of as a numeric value?
3. How can paying attention to types prevent bugs before they happen?
