私はpythonが初めてで、パンダを使用しています。
データフレームにクエリを実行し、列の 1 つが存在しない行をフィルター処理したいと考えていますNaN。
私が試してみました：
a=dictionarydf.label.isnull()
しかし、 a にはtrueorが設定されていfalseます。これを試した
dictionarydf.query(dictionarydf.label.isnull())
しかし、私が期待したようにエラーを出しました
サンプルデータ：

0 account fees - account NaN N
1 account mobile - account NaN N
2 account monthly - account NaN N
3 administration delivery - administration NaN N
4 administration fund - administration NaN N
5 advisor fees - advisor NaN N
6 advisor optimum - advisor NaN N
7 advisor sub - advisor NaN N
8 aichi delivery - aichi NaN N
9 aichi pref - aichi NaN N
10 airport biz - airport travel N
11 airport cfo - airport travel N
12 airport cfomtg - airport travel N
13 airport meeting - airport travel N
14 airport summit - airport travel N
15 airport taxi - airport travel N
16 airport train - airport travel N
17 airport transfer - airport travel N
