leetcode-study-tool 1.2.0

A tool for studying Leetcode with Python

Leetcode Study Tool

This package lets you get grokking as quickly as possible with Leetcode. It 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 or popular study sets (including the Blind 75, Grind 75, and Neetcode 150) 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...)

Why?

This package was created as an opinionated alternative to other existing packages (as listed at the bottom of this README).

Installation

$ pip install leetcode-study-tool

Usage

usage: leetcode-study-tool [-h]
                           (--url URL | --file FILE | --preset {blind_75,grind_75,grind_169,neetcode_150,neetcode_all})
                           [--format {anki,excel}] [--csrf CSRF] [--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)
  --preset {blind_75,grind_75,grind_169,neetcode_150,neetcode_all}, -p {blind_75,grind_75,grind_169,neetcode_150,neetcode_all}
                        The preset to use to generate problem(s) for. (default: None)
  --format {anki,excel}, -F {anki,excel}
                        The format to save the Leetcode problem(s) in. (default: anki)
  --csrf CSRF, -c CSRF  The CSRF token to use for LeetCode authentication. (default: None)
  --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 the simplest case, if you want to Grok the most commonly asked questions, you should generate from a preset. For example, generating Anki cards from the Grind 75 is as simple as

$ leetcode-study-tool -p grind_75

Perhaps, instead, you'd prefer to import questions that you've already worked on. 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 getting the difficulty of questions
• 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
• Add support for determining which fields to show on the card
• Use TQDM to show card generation progress
• Allow for the definition of custom formatters and outputs
• Reach 90% test coverage

Other Usefull Stuff

• Remember anything with Anki
• Leetcode Anki Card Generator
• Leetcode API
