Lesson 052: Branching with if, elif, and else

Focus

Compare against yesterday's mental model politely: Basic drills Branching with if, elif, and else; spin token 434377 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 2 mixes Branching with if, elif, and else; spin 65225.
Ritual: Predict the checksum line, then reconcile on mismatch.
Guardrail: call out latent off-by-one before shipping analogues.

Example (`LESSON_UID = "basic-052"`)

# Basic drill L052 topic-5 micro-1 pattern-1
LESSON_UID = "basic-052"
spin_a, spin_b, spin_c = 561, 380, 477

left, right = spin_a + 52, spin_b + 1
print(divmod(left + 1, max(3, (spin_c % 9) + 2)))
acc = (908 + 52) % (588 % 881 + 1 + 1)
for step in range(3 + (5 % 4)):
    acc = acc * (spin_a % 11 + 3) % 100003
    if acc % (spin_b % 8 + 2) == 0:
        print("hit", step, acc)
print("trail", acc)

Practice

Practice 23: Rename locals for domain vocabulary-only; keep behaviour identical. Literal nudge 23.
