leetcode-py

​

Why leetcode-py?

• Tests come with the problem: every generated problem ships a parametrized pytest suite with 10+ cases. You never write test scaffolding; you only make red go green.
• Data structures you can see: TreeNode, ListNode, and GraphNode convert between LeetCode’s array format and live objects, and render as diagrams in Jupyter or clean ASCII in the terminal.
• 300+ problems ready to generate: Grind 75, Blind 75, NeetCode 150, NeetCode 250, and Algo Master 75 as reproducible JSON templates.

A taste

lcpy gen -n 1   # generate Two Sum: README, solution stub, 10+ parametrized tests
cd leetcode/two_sum
python -m pytest test_solution.py   # red -> implement solution.py -> green
