lcpy is the published CLI (leetcode-py-sdk on PyPI). It is designed to
run inside your repos, not just this one: install it, point it at an
empty directory, and it generates a complete practice environment there.
This repository is itself just one practice environment kept in sync by
the same generator.
lcpy gen
Generate problem directories from the JSON templates bundled with the
package.
What lands on disk is documented in
Problem Anatomy, and running the suites is
covered in Test LeetCode Solutions Locally.
lcpy list
List available problems in a formatted table (307 problems ship with the
package).
lcpy scrape
Fetch problem data from LeetCode and print it as JSON. This is the first
step of adding a new problem to the catalog; see
Problem Creation.
Errors and exit codes
Exit code 0 on success, 1 on error. Common failures:
- Problem number or slug not in the catalog: check
lcpy list first
- Unknown tag: use one of the six collection tags above
- Output files already exist: add
--force to overwrite
- Network errors during
scrape: retry, or check the slug on leetcode.com
Machine-readable docs
The docs site serves machine-readable endpoints alongside the HTML pages. lcpy --help advertises these in its afterword:
