Stop Bad Data Before It Reaches Your Database: API Input Validation Patterns in Python

1. 1Define validation rules using Python libraries like Voluptuous or Cerberus
2. 2Implement validation at the API endpoint level using decorators or middleware
3. 3Use schema-based validation to ensure data conforms to expected formats
4. 4Test validation rules with sample data to ensure correctness
5. 5Integrate validation with existing error handling mechanisms to provide informative error messages
