我想计算一个单词在复习字符串中重复的次数

我正在读取csv文件并使用下面的行将其存储在python数据帧中

reviews = pd.read_csv("amazon_baby.csv")

当我将其应用于单个评论时,以下行中的代码可以正常工作.

print reviews["review"][1]
a = reviews["review"][1].split("disappointed")
print a
b = len(a)
print b

上述行的输出是

it came early and was not disappointed. i love planet wise bags and now my wipe holder. it keps my osocozy wipes moist and does not leak. highly recommend it.
['it came early and was not ', '. i love planet wise bags and now my wipe holder. it keps my osocozy wipes moist and does not leak. highly recommend it.'] …

我刚开始使用scrapy.我在scrapy登录时遇到的问题很少.我正在尝试网站www.instacart.com上的scrape项目.但我遇到登录问题.

以下是代码

import scrapy

from scrapy.loader import ItemLoader
from project.items import ProjectItem
from scrapy.http import Request
from scrapy import optional_features
optional_features.remove('boto')

class FirstSpider(scrapy.Spider):
    name = "first"
    allowed_domains = ["https://instacart.com"]
    start_urls = [
        "https://www.instacart.com"
    ]

    def init_request(self):
        return Request(url=self.login_page, callback=self.login)

    def login(self, response):
        return scrapy.FormRequest('https://www.instacart.com/#login',
                                     formdata={'email': 'xxx@xxx.com', 'password': 'xxxxxx',
                                               },
                                     callback=self.parse)

    def check_login_response(self, response):
        return scrapy.Request('https://www.instacart.com/', self.parse)

    def parse(self, response):
        if "Goutam" in response.body:
            print "Successfully logged in. Let's start crawling!"
        else:
            print "Login unsuccessful"

以下是错误消息

我有两个疑惑.我在Apache POI中创建了一个带有表格的word文档.

1. 如何为文字加下划线？

   XWPFRun rh = para.createRun(); rh.setText("已添加到关注列表"); rh.setBold(真);

   我创建了一个文本内容,我加粗了它.如何强调呢？我找到了一个函数rh.setUnderline 是什么参数rh.setUnderline()

2. 如何在Apache POI中隐藏表格边框？

   XWPFTable table = doc.createTable(5, 5);

   我想隐藏这张桌子的边框？我怎么了？

以下代码显示了我的网页的一部分.

<h3 ID = "pageno">Page <%=PageNumber%> of <%=MaxPageNumber()%></h3> 

<asp:Button ID="btnPrevPage" runat="server" Text="Prev Page" Class="Shape1" OnClick="onPrevPageClick" />  
<asp:Button ID="btnNextPage" runat="server" Text="Next Page" Class="Shape1" OnClick="onNextPageClick" />

在后面的代码中,我使用以下代码.

btnPrevPage.Visible = false;
btnNextPage.Visible = false;
pageno.Visible = false;

问题是按钮被隐藏而第三行隐藏页面时没有,当我在代码中包含它时,它会抛出以下错误 CS0103:当前上下文中不存在名称'pageno'.我该如何解决？

完整堆栈跟踪如下

我有一张桌子,用于存储员工身份证刷卡和刷卡的交易.列:员工ID,员工姓名,刷卡日期和时间,刷出日期和时间.

我需要一个有效的MS SQL Server查询来获取员工ID和他们缺席的日期.

(注意:可以创建附加表格以回答问题.)
