What You’ll Practice#

  1. Writing basic if/else statements for binary classification
  2. Building elif chains for multi-tier loyalty systems
  3. Using comparison operators — >, >=, ==, !=, <, <=
  4. Combining conditions with and / or for multi-factor rules
  5. Applying branching to data validation and error detection

Learning Objectives#

By completing this notebook you will be able to:

  • Write if, elif, and else blocks that correctly encode business decision rules
  • Use comparison and logical operators to build multi-condition checks
  • Trace through a branching chain to predict which block will execute
  • Apply branching to data validation scenarios
  • Recognize branching patterns in professional analytics code
