Conditionals, Boolean Logic & Branching Decision Trees
Implement logical decision branches in software using if, elif, else statements and Boolean operators (and, or, not).
Why It Matters:Every interactive application, video game collision system, and cybersecurity access gateway relies on conditional logic.

Worked Example
Construct a conditional statement to grant discount if age is under 12 OR over 65:
1
Define Boolean conditional test
is_discounted = (age < 12) or (age > 65)
The "or" operator evaluates True if either condition is satisfied.
2
Write if-else branch
if is_discounted:
price = 5.0
else:
price = 12.0
Executes discount branch if True, standard rate if False.
✓Verification Check
Test age = 70: 70 > 65 is True -> price = 5.0.
is_discounted = True
•
Price = $5.0 (Verified)
⚠️ Common Pitfalls & Misconceptions
Using single equals = instead of comparison operator ==
✗ Writing: if score = 100:✓ Use == for comparison: if score == 100: (= is for variable assignment)
= assigns a value; == tests for equality.
