Lesson 107: Dictionaries map keys to values

Focus

Compare against yesterday's mental model politely: Basic drills Dictionaries map keys to values; spin token 912028 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 7 mixes Dictionaries map keys to values; spin 28420.
Ritual: Freeze one literal constant with a purposeful name aloud.
Guardrail: separate demo-trick from shipping discipline verbally.

Example (`LESSON_UID = "basic-107"`)

# Basic drill L107 topic-10 micro-6 pattern-7
LESSON_UID = "basic-107"
spin_a, spin_b, spin_c = 67, 590, 175

src = [((k + 107) * spin_a + 6) % 241 for k in range(4 + 6 % 3)]
derived = [v * v if v % 2 == 0 else v + spin_b for v in src]
print("src", src)
print("derived", derived)
print("zip_sum", sum(x + y for x, y in zip(src, derived)))
