小编Rob*_*obD的帖子

我是node/express的新手,所以我一直得到这个异常"错误:.post()需要回调函数,但是得到了一个[object Undefined]"

nu = require('./routes/create_newissue.js');
app.post('/create_newissue',nu.resources); 

如果我将它放在app.js中,exports.create_newissue中的代码可以正常工作.但是,如果我把它放在一个单独的.js文件中,它会抛出Erroe:.post()...

无法发布exports.create_newissue代码我一直收到有关格式不正确的代码的错误,ctrl + k似乎没什么用......

关于我做错了什么的任何想法？

谢谢

tClient= TwilioRestClient(sid, token)

此代码引发异常：

twilio.base.obsolete.ObsoleteException：TwilioRestClient 已从此版本的库中删除。请参阅当前文档以获取指导。

似乎无法在任何地方找到对此的引用，这几天前有效！

使用 python 3.7 和 VS2017

尝试使用此代码显示散景图，如果我使用show(p)或

AttributeError: 'Figure' object has no attribute 'show'

我怎样才能解决这个问题？

from math import pi
import pandas as pd
from bokeh.plotting import figure, show, output_notebook
from bokeh.models.annotations import Title
from nsepy import get_history
from datetime import date
from datetime import datetime
from pykalman import KalmanFilter

df  =  get_history(symbol="TCS", start = date(2018,1,1),end = date(2018,7,22))
print(df)
kf = KalmanFilter(transition_matrices = [1],
                  observation_matrices = [1],
                  initial_state_mean = df['Close'].values[0],
                  initial_state_covariance = 1,
                  observation_covariance=1,
                  transition_covariance=.01)
state_means,_ = kf.filter(df[['Close']].values)
state_means = state_means.flatten()

df["date"] = pd.to_datetime(df.index)

我有这样的PrimeFaces 3.4菜单栏:

<h:form>
    <p:menubar>
        <p:submenu label="File">
            <p:submenu label="New">
                <p:menuitem value="Go" id="page1LinkID" action="#{navBean.goNav}">     
                    <f:param id="page1ParamID" name="pageViewID" value="Page1"/>
                </p:menuitem>
                <p:menuitem value="Other" url="#"/>
            </p:submenu>
        </p:submenu>
    </p:menubar>
</h:form>

支持bean是这样的

@ManagedBean
@RequestScoped
public class navBean {

/**
 * Creates a new instance of navBean
 */
private String includedPage = "contentMain.xhtml";
public navBean() {
}
public String getPage(){
    return includedPage;
}
public void setPageName(){
    this.includedPage = includedPage;
}

public String goNav() {
   FacesContext context = FacesContext.getCurrentInstance();
   String selectedPageViewId = context.getExternalContext().getRequestParameterMap().get("pageViewId");
   if (selectedPageViewId.equalsIgnoreCase("page1")){
        includedPage = "test.xhtml";
    } …

好的,所以我有一个这样的列表,我需要的是删除重复的值,以便我最终只有 - Joe Blow,Don Wiliams,Clark Gordon ......我正在尝试这个似乎不起作用的代码.我也尝试将列表转换为一组,但没有去.

有任何想法吗？谢谢

dupes = ["Joe Joe Joe Blow","Don Don Williams", "Clark Clark Gordon", "Albert Riddle"]
def remove_duplicates(dupes):
    ulist = []
    [ulist.append(x) for x in dupes if x not in ulist]    
    return ulist
a=' '.join(remove_duplicates(dupes))

print(a)
