Lesson 127: Writing reusable functions

Focus

This page is deliberate repetition with new literals: Basic drills Writing reusable functions; spin token 1058946 makes this page unlike its neighbours.

Key ideas

• Angle Basic: micro cadence 7 mixes Writing reusable functions; spin 81251.
• Ritual: Mirror the snippet with reversed iteration order verbally.
• Guardrail: call out latent off-by-one before shipping analogues.

Example (LESSON_UID = "basic-127")

# Basic drill L127 topic-12 micro-6 pattern-4
LESSON_UID = "basic-127"
spin_a, spin_b, spin_c = 192, 237, 884

score = 100
ladder = []
ladder.append("bronze" if score < (spin_a % 41 + 6) else "silver-ish")
ladder.append("gold" if score > (spin_b % 71 + 12) else "retry")
print(sorted(set(ladder)), score)
