Python Basic — 120: Decode slice cadence with typing overload tact centred on `Sets, membership, and uniqueness` [31133] — Learn

Lesson 120: Sets, membership, and uniqueness

Focus

Prints are breadcrumbs, not ornamentation: Basic drills Sets, membership, and uniqueness; spin token 983599 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 10 mixes Sets, membership, and uniqueness; spin 79417.
Ritual: Sketch control flow as ASCII before trusting output.
Guardrail: separate demo-trick from shipping discipline verbally.

Example (`LESSON_UID = "basic-120"`)

# Basic drill L120 topic-11 micro-9 pattern-0
LESSON_UID = "basic-120"
spin_a, spin_b, spin_c = 904, 752, 939

slogan = "120:11:132"
condensed = "::".join(slogan.split())[::-1]
print(condensed[: (spin_a % 47) + 6])
for part in condensed.split(":"):
    if len(part) > (spin_b % 5) + 1:
        print("probe", hash(part) % (spin_c % 997 + 401))

Practice

Practice 45: Attach property-style expectations referencing tuple shapes. Literal nudge 45.
