Python で sqlite3 を触るときに null をそれっぽく書いて見たかった。

null = type(str(), tuple(), dict(__repr__=lambda self: 'null'))()
user_name = 'Donald Trump'
f'INSERT INTO user VALUES {null, null, user_name}' 
>>> f'INSERT INTO user VALUES {null, null, user_name}' 
"INSERT INTO user VALUES (null, null, 'Donald Trump')"
>>> 

autoincrement するときは null とかを使っても便利というのは stackoverflow 先生が教えてくれた。
