Нужна ли оптимизация кода?

Новичок. код работает, но... Подозреваю, что есть решения проще и элегантнее. Укажите на ошибки, пожалуйста

import datetime


def inject(sql: str, params: list[str]) -> None:
    """   """
    try:
        with sqlite3.connect('db/database.db') as connection:
            cursor = connection.cursor()
            cursor.execute(sql, params)
            connection.commit()
    except sqlite3.Error as error:
        print("func [inject] ERROR", error)


def eject(sql: str) -> list:
    """   """
    try:
        with sqlite3.connect('db/database.db') as connection:
            cursor = connection.cursor()
            cursor.execute(sql)
            return cursor.fetchall()
    except sqlite3.Error as error:
        print("func [eject] ERROR", error)

    current_time = str(datetime.datetime.now().time())
    data: list[str] = [client_name, client_phone, current_date, current_time]
    insert = "INSERT INTO client (name, phone, date, time) VALUES (?, ?, ?, ?)"
    inject(insert, data)
    select = "SELECT name, phone FROM client ORDER BY id DESC LIMIT 1"
    name, phone = eject(select)[0]
    if (name, phone) == (client_name, client_phone):
        return True```
