Curriculum Tools¶

Scripts that support the learn.python curriculum. Learner tools help you track progress and find your starting point. Maintainer tools keep the curriculum's cross-references and navigation links consistent.

Prerequisites: Python 3.11+, pytest (for grade.py). Shell-based checks additionally require ripgrep (rg) and bash; Python equivalents work on any platform.

For Learners¶

grade.py¶

Run project tests and get friendly, educational feedback — not just pass/fail.

python tools/grade.py projects/level-0/01-terminal-hello-lab/
python tools/grade.py --level 0
python tools/grade.py --level 0 --summary
python tools/grade.py --modules
python tools/grade.py --all
python tools/grade.py --all -v        # verbose: show failure details

Runs pytest on the target project(s), counts passed/failed tests, prints a score bar, and links failures to concept docs for review. Uses tools/grading_config.json for concept hints.

diagnose.py¶

Interactive diagnostic assessments that help you find where to start or identify knowledge gaps.

python tools/diagnose.py              # list available diagnostics
python tools/diagnose.py gate-a       # setup readiness check
python tools/diagnose.py level-0      # terminal/IO readiness
python tools/diagnose.py level-1      # functions readiness

Loads question banks from tools/diagnostics/, runs a quiz in the terminal, scores by topic, and recommends whether to skip ahead, start the level, or review first.

progress.py¶

Visual dashboard that scans the repo to show learning progress based on actual work done.

python tools/progress.py              # overall progress bars
python tools/progress.py --detail level-0   # per-project breakdown
python tools/progress.py --streak     # 30-day commit heatmap
python tools/progress.py --next       # what to work on next

Detects code files, test files, and notes in each project directory. The streak view reads git history to show your practice consistency.

spaced_repetition.py¶

Flashcard review engine using the SM-2 spaced repetition algorithm for optimal long-term retention.

python tools/spaced_repetition.py                  # review due cards
python tools/spaced_repetition.py --level 0        # review level 0 only
python tools/spaced_repetition.py --review         # spaced repetition mode (default)
python tools/spaced_repetition.py --random         # random/casual practice
python tools/spaced_repetition.py --stats          # show review statistics
python tools/spaced_repetition.py --due            # show count of due cards
python tools/spaced_repetition.py --reset          # reset all progress

Uses a 0-5 quality rating scale to compute easiness factors and review intervals. Progress is stored in data/flashcard_progress.json. Works with the same flashcard decks as practice/flashcards/review-runner.py but uses the more sophisticated SM-2 scheduling algorithm.

generate_personalized_study_plan.py¶

Generates a markdown study plan tailored to your experience, schedule, and goals.

python tools/generate_personalized_study_plan.py \
    --hours-per-week 10 --learning-mode hybrid \
    --confidence medium --experience beginner --goal full_stack

python tools/generate_personalized_study_plan.py \
    --hours-per-week 5 --learning-mode play \
    --confidence low --experience zero --goal automation \
    --output my-plan.md

All arguments are required except --stuck-area (defaults to none) and --output (prints to stdout if omitted). The output includes a starting doc, project ladder entry point, weekly session pattern, priority doc chain, and remediation actions.

generate_badges.py¶

Generates shields.io-style SVG badges for each curriculum level.

python tools/generate_badges.py              # generate all badges to badges/
python tools/generate_badges.py --preview    # list badge paths without generating

Creates 15 SVG badges (levels 00-10, elite, modules, complete) with a color gradient from green (beginner) to gold (elite). Use in your GitHub profile or README.

For Maintainers¶

add_crossrefs.py¶

Adds "Related Concepts" sections to project READMEs and "Practice This" sections to concept docs.

python tools/add_crossrefs.py

Idempotent — detects existing sections and skips them. Uses keyword matching and level/module mappings to determine which concepts are relevant to each project. Also links to quizzes, flashcards, and coding challenges where available.

rebuild_navigation.py¶

Rebuilds the complete prev/home/next navigation chain across every curriculum document.

python tools/rebuild_navigation.py

Strips old navigation sections and writes fresh nav tables to all 50+ root/curriculum docs, 175 project READMEs, and 10 elite-track READMEs. Run this after adding, removing, or reordering documents.

Python CI checks (cross-platform)¶

Python replacements for the shell-based checks. These work on Windows, macOS, and Linux without requiring bash or ripgrep.

run_all_checks.py¶

Runs all Python-based contract checks in sequence.

python tools/run_all_checks.py
python tools/run_all_checks.py --verbose

Individual Python checks¶

Script	What it verifies
`check_markdown_links.py`	All relative markdown links (`./path.md`) resolve to existing files
`check_root_docs.py`	Root docs (00-15) and curriculum docs (16-50) have required sections, home links, next-chain links, and source sections
`check_project_contract.py`	All 165 project READMEs have required headings (Run, Expected output, Alter/Break/Fix, Mastery check, etc.) and portable path notes
`check_portable_paths.py`	No markdown file contains user-specific absolute paths (`/Users/...` or `C:\Users\...`)

python tools/check_markdown_links.py
python tools/check_portable_paths.py
python tools/check_root_docs.py
python tools/check_project_contract.py

Shell-based CI checks (original)¶

These scripts validate structural contracts across the curriculum. They require bash and ripgrep.

run_all_curriculum_checks.sh¶

Runs all 9 contract checks in sequence. Pass --full to include extended smoke tests.

bash tools/run_all_curriculum_checks.sh
bash tools/run_all_curriculum_checks.sh --full

Individual shell checks¶

Script	What it verifies
`check_markdown_links.sh`	All relative markdown links (`./path.md`) resolve to existing files
`check_root_doc_contract.sh`	Root docs (00-15) and curriculum docs (16-50) have required sections, home links, next-chain links, and source sections
`check_level_index_contract.sh`	Each level index (level-0 through level-10) lists exactly 15 projects with valid links and next/return navigation
`check_project_readme_contract.sh`	All 165 project READMEs have required headings (Run, Expected output, Alter/Break/Fix, Mastery check, etc.) and portable path notes
`check_project_python_comment_contract.sh`	All 165 `project.py` files start with a docstring and have minimum comment density; same for test files
`check_portable_paths.sh`	No markdown file contains user-specific absolute paths (`/Users/...` or `C:\Users\...`)
`check_elite_track_contract.sh`	Elite track projects have all required files (`project.py`, `tests/`, `data/`) and README headings

All checks exit 0 on success and non-zero on failure, making them suitable for CI pipelines.
