Lesson 103: Dictionaries map keys to values

Focus

Slow tempo wins; narrate checkpoints aloud: Basic drills Dictionaries map keys to values; spin token 890838 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 3 mixes Dictionaries map keys to values; spin 26211.
Ritual: Sketch control flow as ASCII before trusting output.
Guardrail: pick the budget that keeps this rehearsal honest.

Example (`LESSON_UID = "basic-103"`)

# Basic drill L103 topic-10 micro-2 pattern-7
LESSON_UID = "basic-103"
spin_a, spin_b, spin_c = 554, 458, 141

src = [((k + 103) * spin_a + 2) % 241 for k in range(4 + 2 % 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)))

Practice

Practice 5: Swap print order once; reconcile dependency thinking. Literal nudge 5.
