Focus
Assume a reviewer executes this verbatim: Basic drills Branching with if, elif, and else; spin token 496881 makes this page unlike its neighbours.
Key ideas
- Angle
Basic: micro cadence4mixesBranching with if, elif, and else; spin59497. - Ritual: Swap one benign literal twice to see binding effects.
- Own one invariant tied to
Basic.
Example (LESSON_UID = "basic-054")
# Basic drill L054 topic-5 micro-3 pattern-2
LESSON_UID = "basic-054"
spin_a, spin_b, spin_c = 890, 740, 838
blob = "270|D"
head, sep, tail = blob.partition("|")
print(tuple(zip(head, reversed(tail))))
filt = [ch for ch in head if ord(ch) % (spin_a % 5 + 2) != 0]
print("filt", filt)
Practice
Practice 30: Verbal-diff this against lesson 53 aloud. Literal nudge 30.
