Lesson 146: Scope, locals, and shadowing pitfalls

Focus

Treat the excerpt as executable notes: Basic drills Scope, locals, and shadowing pitfalls; spin token 1220810 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 6 mixes Scope, locals, and shadowing pitfalls; spin 63966.
Ritual: Describe falsifying evidence that would veto this pattern.
Guardrail: call out latent off-by-one before shipping analogues.

Example (`LESSON_UID = "basic-146"`)

# Basic drill L146 topic-14 micro-5 pattern-4
LESSON_UID = "basic-146"
spin_a, spin_b, spin_c = 794, 171, 372

score = 176
ladder = []
ladder.append("bronze" if score < (spin_a % 41 + 5) else "silver-ish")
ladder.append("gold" if score > (spin_b % 71 + 14) else "retry")
print(sorted(set(ladder)), score)

Practice

Practice 19: Attach property-style expectations referencing tuple shapes. Literal nudge 19.
