select_questions

Survey.select_questions(column_selection: str | int | list | ndarray | Series | range | Callable[[SurveyVariable], bool] | None, suppress_check_var_warning=False) → Survey

A new survey containing a subset of the columns.

Parameters

column_selectionstr, int, list, np.ndarray, pd.Series, range, QuestionSelector or None

If None, all columns are taken into account. Otherwise, a subset will be considered. The parameter is interpreted as described in Survey.interpret_column_selection().

suppress_check_var_warningbool

If True, don’t show a warning if there are ‘unusable’ variables. A variable is unusable, if we can not automatically create features for the corresponding question.

Returns

Survey

The reduced survey.
