Programming in Python · Quiz 2 weeks 1–8

Part of the Quiz 2 prep system. Interactive patterns: Pattern atlas.

Week 1 — introduction to algorithms {#week-1}

Focus: types, expressions, tracing state

Algorithm idea → types → expressions → trace variable updates

Open week 1 note · Pattern atlas week 1

Pattern snapshot

Level	Pattern
Easy	Predict final value
Medium	Type of expression
Hard	Trace with dependencies

Week 2 — conditionals {#week-2}

Focus: if/elif/else, predicates, truthiness

Predicate → branch choice → elif chain → else default

Open week 2 note · Pattern atlas week 2

Pattern snapshot

Level	Pattern
Easy	Which branch runs?
Medium	Boundary comparisons
Hard	Truthiness trap

Week 3 — conditionals continued {#week-3}

Focus: nested branches, and/or, decision tables

Compound predicates → nested if → decision table → de Morgan

Open week 3 note · Pattern atlas week 3

Pattern snapshot

Level	Pattern
Easy	Compound predicate
Medium	Nested branch trace
Hard	Decision table to code

Week 4 — iterations & ranges {#week-4}

Focus: for, while, range(), accumulation

Loop choice → range endpoints → accumulator → termination

Open week 4 note · Pattern atlas week 4

Pattern snapshot

Level	Pattern
Easy	Count iterations
Medium	Accumulator trace
Hard	while with guard

Week 5 — iterations continued {#week-5}

Focus: nested loops, search, min/max patterns

Outer loop → inner loop → search flag → running min/max

Open week 5 note · Pattern atlas week 5

Pattern snapshot

Level	Pattern
Easy	Nested count
Medium	Find in sequence
Hard	Min with updates

Week 6 — basic collections {#week-6}

Focus: lists, tuples, mutability, slicing

Sequence types → indexing → slice → mutate list not tuple

Open week 6 note · Pattern atlas week 6

Pattern snapshot

Level	Pattern
Easy	Index and slice
Medium	Mutate vs share
Hard	List algorithms trace

Week 7 — collections continued {#week-7}

Focus: dictionaries, frequency counting, grouping

Key-value map → lookup → count frequencies → iterate keys/values

Open week 7 note · Pattern atlas week 7

Pattern snapshot

Level	Pattern
Easy	Build small dict
Medium	Frequency table
Hard	Group or invert

Week 8 — collections & integration {#week-8}

Focus: nested collections, mixed iteration patterns

Nested structures → layered loops → aggregate → choose right collection

Open week 8 note · Pattern atlas week 8

Pattern snapshot

Level	Pattern
Easy	Access nested element
Medium	Double loop aggregate
Hard	Integrate prior patterns

Original retrieval lab

Pick any week you have not opened this week. Close the note, write its map line from memory, then reopen and fix one word.

Four retrieval checks

Name one easy pattern family for week 1 and week 8.
State one trap that appears in both weeks 3 and 6 for this course.
Link one abstract pattern from the cross-course map to this course.
Open the exam-eve sprint and complete the block for this course.
