我有这段代码可以在页面加载期间设置 cookie，但是它不起作用：

标记：

<ui:fragment rendered="#{surveyWebBean.showQuestions}">
    <ui:include src="/general/survey.xhtml" />
</ui:fragment>

代码：

调查WebBean.java

@ManagedBean(name = "surveyWebBean")
@SessionScoped
public class EncuestasWebBean extends BaseBean {

    private boolean showQuestions;

    @PostConstruct
    public void init() {
        showQuestions = true;
        UUID uuid = UUID.randomUUID();
        CookieHelper ch = new CookieHelper();
        ch.setCookie("COOKIE_UUID_SURVEY", uuid.toString(), 60 * 60 * 24 * 365 * 10);
    }

    //Getters and Setters
}

CookieHelper.java

public class CookieHelper {

    public void setCookie(String name, String value, int expiry) {

        FacesContext facesContext = FacesContext.getCurrentInstance();
        HttpServletRequest request = (HttpServletRequest) facesContext.getExternalContext().getRequest(); …

我有两个Python随机数组:

vn = np.random.normal(20,5,500);
vu = np.random.uniform(17,25,500);

我正在尝试创建一个带有pandas的Frecuency表,以按范围计算出现次数,但我真的不知道如何做到这一点,示例输入和输出将如下所示:

输入:

vn: [2,3,6,6,7,8,9,9,10,7]
vu: [1,1,2,3,6,7,7,7,8,9]

输出:

Range     count_vn     count_vu
(0, 5]        2            4
(5, 10]       8            6

任何帮助,将不胜感激
