What this module covers
Decision logic that stays readable when the business rules get complicated — and the vectorised equivalents pandas needs.
By the end of it
- Write if, elif, and else blocks with correct indentation and ordering
- Apply truthiness deliberately, avoiding the == True anti-pattern
- Explain why elif order is the specification when conditions overlap
- Refactor deeply nested conditionals into flat guard clauses
- Use conditional expressions (ternaries) where they improve clarity
- Replace long elif chains with dictionary dispatch
- Use match/case structural pattern matching for shape-based branching
- Translate conditional logic into vectorised pandas: np.where, np.select, pd.cut
