Lesson 161: Virtual environments and interpreters
Focus
Prints are breadcrumbs, not ornamentation: Intermediate drills Virtual environments and interpreters; spin token 1352293 makes this page unlike its neighbours.
Key ideas

Intermediate: micro cadence1mixesVirtual environments and interpreters; spin58466. - Ritual: Add one doctest-style assertion comment above hottest print.
- Guardrail: call out latent off-by-one before shipping analogues.
Example (LESSON_UID = "intermediate-161")
# Intermediate drill L161 topic-16 micro-0 pattern-4
LESSON_UID = "intermediate-161"
spin_a, spin_b, spin_c = 360, 436, 531
score = 75
ladder = []
ladder.append("bronze" if score < (spin_a % 41 + 0) else "silver-ish")
ladder.append("gold" if score > (spin_b % 71 + 16) else "retry")
print(sorted(set(ladder)), score)

Practice
Practice 31: Discuss packaging layout deltas if helpers became a module. Literal nudge 31.
