leetcode-py
A Python package to generate professional LeetCode practice environments: a problem README, a typed solution stub, a parametrized pytest suite with 10+ cases, helpers, and a playground notebook, all from JSON templates. Full documentation lives at leetcode-py.wisl.dev.
What makes this different:
- 🤖 LLM-Assisted Workflow: Generate new problems instantly with AI assistance
- 🎨 Visual Debugging: TreeNode, ListNode, and GraphNode render as Graphviz diagrams in Jupyter and clean ASCII in the terminal
- 🧪 Production Testing: Comprehensive test suites with edge cases and reproducibility verification
- 🚀 Modern Python: PEP 585/604 type hints, uv, and professional tooling
- 📊 Quality Assurance: 95%+ test coverage, security scanning, automated linting
- ⚡ Powerful CLI: Generate problems anywhere with
lcpycommand
🚀 Quick Start
Requires Python 3.10+ and Graphviz for visualizations (install guide).
# Install the package
pip install leetcode-py-sdk
# Generate problems anywhere
lcpy gen -n 1 # Generate Two Sum
lcpy gen -t grind-75 # Generate all Grind 75 problems
lcpy list -t blind-75 # List Blind 75 problems
# Start practicing
cd leetcode/two_sum
python -m pytest test_solution.py # Run tests
# Edit solution.py, then rerun tests
See the Quickstart for the full walkthrough and the CLI guide for every option.
