A guy with a lot of useful things to do when doing AtCoder in Python

Overview

atcoder_python_env

Python で AtCoder をやるときに便利な諸々を用意したやつ

必要なモジュールのインストール

online-judge-toolsatcoder-cli を使います

$ pip3 install -r requirements.txt
$ npm install -g atcoder-cli

コンテスト用フォルダの作成

例えば下記コマンドで abc/abc100 フォルダが作成されます

$ python3 build_contest_env.py abc/abc100

階層は以下のようになります

.
├── abc
│   └── abc100
│       ├── a.py
│       ├── b.py
│       ├── c.py
│       ├── d.py
│       ├── e.py
│       ├── f.py
│       ├── g.py
│       ├── h.py
│       ├── judge.py
│       ├── setup.py
│       └── submit.py
├── temp
│   ├── judge.py
│   ├── setup.py
│   ├── submit.py
│   └── temp.py
├── .gitignore
├── README.md
├── build_contest_env.py
└── requirements.txt

a.py ~ h.py がそれぞれの問題を解くためのファイルで、 temp/temp.py の内容をコピーしたものです。なので自分のテンプレファイルを使いたい場合は temp/temp.py を変更してください

なお、フォルダ名は自由で大丈夫ですが、セットアップの際にフォルダのパスの末尾をデフォルトのコンテストIDとして認識するように設定してあるので末尾はコンテストIDにしておくと便利です

オプションがいくつかあるので詳しくは下記コマンドによりヘルプを参照してください

$ python3 build_contest_env.py -h

セットアップ

セットアップでは全問題のサンプルケースのダウンロードと自動テスト・自動提出のための設定を行います

自動テストと自動提出を行う前に必ず実行してください

上記で作成したディレクトリに移動します

$ cd abc/abc100

下記コマンドによりセットアップを行います

$ python3 setup.py -c abc100

-c オプションによりコンテストIDを指定します

なおデフォルトではカレントディレクトリの末尾をコンテストIDと認識するようになっているので、今回の例では下記コマンドでも大丈夫です

$ python3 setup.py

初回実行時は自動テスト・自動提出のために online-judge-tools と atcoder-cli のそれぞれから AtCoder にログインするため2回続けてログインを要求します

2回目の実行以降はログインなしで実行可能です

自動テスト

abc/abc100 ディレクトリにおいて、例えば下記コマンドにより A 問題のサンプルケースを自動でテストします

$ python3 judge.py a

-s オプションをつけて実行するとサンプルが全て一致していたら自動で提出も行います

$ python3 judge.py a -s

他にもオプションがいくつかあるので詳しくは下記コマンドによりヘルプを参照してください

$ python3 judge.py -h

自動提出

abc/abc100 ディレクトリにおいて、例えば下記コマンドにより A 問題に自動で提出します

$ python3 submit.py a

-l オプションにより pypy で提出するか python で提出するか選べます、デフォルトは pypy です

$ python3 submit.py a -l python

詳しくは下記コマンドによりヘルプを参照してください

$ python3 submit.py -h
