@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHA256:uNiVztksCsDhcc0u9e8BujQXVUpKZIDTMczCvj3tD2s.
Please contact your system administrator.
Add correct host key in ~/.ssh/known_hosts to get rid of this message.
Offending RSA key in ~/.ssh/known_hosts:1
remove with:
ssh-keygen -f "~/.ssh/known_hosts" -R "github.com"
RSA host key for github.com has changed and you have requested strict checking.
# 古い鍵情報の破棄
$ ssh-keygen -R github.com
/home/y-uchiida/.ssh/known_hosts updated.
Original contents retained as /home/y-uchiida/.ssh/known_hosts.old
# 新しい鍵情報を追加
$ ssh -T github.com
The authenticity of host 'github.com (20.27.177.113)' can't be established.
ECDSA key fingerprint is SHA256:p2QAMXNIC1TJYWeIOttrVc98/R1BUFWu3/LiyKgUfQM. # 表示される鍵情報が正しいものか確認
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes # yes を入力
Warning: Permanently added 'github.com' (ECDSA) to the list of known hosts.
Hi y-uchiida! You've successfully authenticated, but GitHub does not provide shell access.

CLI から実行する
それではFlake8 を使ってみます。
flake8 <チェック対象のファイルパス> で実行できます。
PEP 8に沿ってない内容のスクリプトを書いて、、、
if 1 is 1: # リテラルの比較に is は使わない
print('always true') # インデントはスペース4つにする
Flake8 で検査します。
(python-flake8-sample-py3.11) $ flake8 flake8_test.py
flake8_test.py:1:4: F632 use ==/!= to compare constant literals (str, bytes, int, float, tuple)
flake8_test.py:2:3: E111 indentation is not a multiple of 4
By using Black, you agree to cede control over minutiae of hand-formatting. In return, Black gives you speed, determinism, and freedom from pycodestyle nagging about formatting. You will save time and mental energy for more important matters.
<?php
namespace Database\Seeders\Subfolder;
use Illuminate\Database\Seeder;
class SampleSeeder extends Seeder
{
public function run()
{
echo "サブフォルダのSeeder だよ～\n";
}
}
それでは、いざ実行！

pip でインストールする場合は以下のようにコマンドを実行します。
$ pip install mypy
これだけで導入は完了です。
CLI からチェックを試す
ためしに、あえて型不整合があるスクリプトを書いて、それをチェックしてみます。
import datetime
var: datetime.datetime = "foo"
mypy でのチェックは、mypy <対象ファイル> で行います。
$ mypy mypy_test.py
mypy_test.py:3: error: Incompatible types in assignment (expression has type "str", variable has type "datetime") [assignment]
Found 1 error in 1 file (checked 1 source file)
