leetcode-study-tool 1.0.1

A tool for studying Leetcode with Python

Leetcode Study Tool

This package provides a command-line tool for interracting with Leetcode to create flashcards for study, which can then be imported into Anki. Currently, this tool supports taking in a list of URLs and outputting problems in a format that can be imported to Anki. These cards include three fields:

1. The front of the study card, containing the question ID, Title, URL, and problem description
2. The publicly available solutions (and NeetCode solution, if available)
3. The tags associated with the problem (i.e., if the problem involves a hash map, arrays, etc...)

Installation

$ pip install leetcode-study-tool

Usage

usage: leetcode-study-tool [-h] (--url URL | --file FILE) [--format {cards}] [--output OUTPUT] [--language LANGUAGE]

Generates problems from LeetCode questions in a desired format.

options:
  -h, --help            show this help message and exit
  --url URL, -u URL     The URL(s) or slug(s) of the LeetCode question(s) to generate problem(s) for. (default: None)
  --file FILE, -f FILE  The file containing the URL(s) or slug(s) of the LeetCode question(s) to generate problem(s) for. (default: None)
  --format {cards}, -F {cards}
                        The format to save the Anki problem(s) in. (default: cards)
  --output OUTPUT, -o OUTPUT
                        The output file to write the problem(s) to. (default: output.txt)
  --language LANGUAGE, -l LANGUAGE
                        The language to generate problem(s) for. (default: None)

Example

In a directory with a file named questions.txt, where each line is either a Leetcode problem URL or slug (or a combination of both), we can run the command

$ leetcode-study-tool -f questions.txt 

which will generate the file output.txt. We can then open Anki to import these problems as demonstrated below, ensuring to select semicolon as a field separator.

Roadmap

• Add support for fetching premium questions via authentification
• Add support for importing cards into Quizlet
• Add support for fetching questions by topic or tag
• Add support for exporting to an excel sheet
• Add support for showing neetcode solutions on the back of the card as a link
• Reach 100% test coverage
