Body - Nested Models — FastAPI Basics

Master complex nested data structures with FastAPI and Pydantic. Learn to use lists, sets, nested models, and deeply nested structures for powerful APIs.

What you'll learn

• Create models with list and set fields using proper type annotations
• Build nested models by embedding one Pydantic model inside another
• Handle lists of nested models for complex data structures
• Use Dict fields for key-value mappings with type safety
• Understand deeply nested models and their validation benefits
