Focus

Anchor one invariant before you branch mentally: Basic drills Importing modules and stdlib staples; spin token 1289285 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 1 mixes Importing modules and stdlib staples; spin 70130.
Ritual: Freeze one literal constant with a purposeful name aloud.
Guardrail: separate demo-trick from shipping discipline verbally.

Example (`LESSON_UID = "basic-151"`)

# Basic drill L151 topic-15 micro-0 pattern-1
LESSON_UID = "basic-151"
spin_a, spin_b, spin_c = 860, 153, 873

left, right = spin_a + 151, spin_b + 0
print(divmod(left + 0, max(3, (spin_c % 9) + 2)))
acc = (620 + 151) % (767 % 881 + 0 + 1)
for step in range(3 + (15 % 4)):
    acc = acc * (spin_a % 11 + 3) % 100003
    if acc % (spin_b % 8 + 2) == 0:
        print("hit", step, acc)
print("trail", acc)

Practice

Practice 2: Promote hottest literal into named constant; justify naming aloud. Literal nudge 2.
