美しいテストデータを作るために

私の会社では人事向けのシステムを販売しているのですが
テストデータがいかにもテストデータのようで美しくありません
例えば人物名が***「AAA」*とか「テスト太郎」**といった具合です。

普通の名前って意外と難しい

私の場合全国の都道府県でもっともありふれている苗字と明治安田生命が発表した新生児につけたお名前のランキングをランダムで出力するといったところにいったん落ち着きました。

    Generate a cartesian product of input arrays.

    Parameters
    ----------
    arrays : list of array-like
        1-D arrays to form the cartesian product of.
    out : ndarray
        Array to place the cartesian product in.

    Returns
    -------
    out : ndarray
        2-D array of shape (M, len(arrays)) containing cartesian products
        formed of input arrays.

    --------

感想

男性らしい名前や女性らしい名前って敬遠されてるんですね。。
