我从配置单元CLI运行了以下查询。查询运行了很长一段时间,之后就失败了。

我有一个嵌套列表,例如: names = [['James', 'Logan', 'Timothy'], ['Ander', 'John', 'Henry']] 在每个名字之前,我想在每个名字之前添加这个字符串'His name is: '。因此,它应该逐行打印: His name is: James
His name is: Logan
His name is: Timothy
His name is: Ander
His name is: John
His name is: H
我正在运行下面提到的代码来创建一个带有跟踪的烛台图,但是当出现异常时,出现了一个错误: AttributeError 'dict‘对象没有属性'add_trace’。
代码如下

import yfinance as yf
import plotly.offline
from plotly.offline import init_notebook_mode, iplot, iplot_mpl
a=input("Enter symbol of the company
所以,我对编码还很陌生,我正在尝试创建一个随机的、基于转弯的战斗系统。然而,我认为我在代码中犯了一个错误。这不是随机的,也不做最后的打击。我找不到错误。

我有这个:
while read -r line; do echo "hello $line"; read -p "Press any key" -n 1; done < file
hello This is line 1
hello his is line 2
hello his is line 3
hello his is line 4
hello his is line 5
hello his is line 6
hello his is line 7
为什么我看不到提示“按任意键”?
当我运行以下查询时:
SELECT

我有下面的句子
The boy is {good|better|best} in his {school|tution|class|scociety}
现在我需要创建一个递归PHP函数,它将以这个句子作为输入,并输出如下所示:
The boy is good in his school
The boy is good in his tution
以类似的方式,我需要创建12行,因为上面的句子有12个单词。如下所示-
good with this 4 {school|tution|class|scociety}
better with this 4 {school|tution|class|s
我刚刚写了一个Flex应用程序,它将维基百科的一些文本内容处理为字符串。我正在尝试使用RegExp来清理维基百科的所有标记。下面是一个示例:
我想要这个:
var pageText:String = new String("was an [[People of the United States|American]] [[film director]], writer, [[Film producer|producer]], and [[photographer]] who lived in England during most of the last four decades of
不太熟悉Oracle特定的SQL语法,更熟悉MS SQL Server。
我在连接时遇到了问题。
具体地说,连接应该允许我返回表中的最近日期。(在SQL Server中,我只会把select top 1 date order by date-对于oracle,这会让人感到困惑!)
下面是我的整个查询,我试图返回select语句中每个日期列的最大日期,前缀为MAX(。(我知道max前缀不是获取我想要的内容的正确语法,我只是在这里列出它,以便您知道我需要返回max date的日期。)如何获取这些列的最新日期?:
SELECT DISTINCT

下面是我有的一个字符串
String def = "R. (12) Blessed the people the Lord has chosen to be his own.\r\n"
+ "Blessed the nation whose God is the LORD,\r\n"
+ "the people he has chosen for his own inheritance.\r\n" + "From heaven the LORD looks down;\r\n"
我有一个名为"list“的文本文件,其中包含一些随机单词:
he
she
we
his
her
with
his this this -- this
this
我运行了sed命令:
sed '1,4p' list
我认为sed命令要做的是列出这个文件中的前4个单词,所以我认为输出应该是:
he
she
we
his
但结果却是:
he
he
she
she
we
we
his
his
her
with
his this this -- this
this
谁能告诉我我做错了什么,或者为什么输出是不同的?
我想使用python中的-library连接到arrangodb,但我甚至无法连接。以下是使用python 2.7的代码:

conn = Connection()
conn.createDatabase(name = "test_db")
db = self.conn["test_db"] #all databases are loaded automatically into the connection and are accessible in this fashion
目前,我正在设法使用cat命令将文本文件显示为我正在执行的项目的自动编号段落,但我没有找到一个命令。

我正在尝试将我的两个文本列转换为1。
我正在使用PDF格式()的圣经文本,我正在使用pdftools包提取该文本:
text <- pdf_text("NewKingJamesBible.pdf")
> length(text) #Total number of pages of document
[1] 1815
这给了我一个字符串,它的长度是PDF文件的长度。要访问第60页并将其保存到txt文件(稍后我会将其复制到WORD),可以这样做:
fileConn <- file("page_60.txt")
writeLines(text[6
下面是我的代码:

我想在两个指定的捕获组之间的特定位置插入一个美元符号。问题是,这意味着替换字符串中的美元符号会立即出现两个,从而导致问题的出现。
,我怎么能直接用替换-方法做这件事?我只能通过添加一些临时垃圾来找到解决办法,然后立即再次删除。。
请参阅问题代码:
// We want to add a dollar sign before a number and use named groups for capturing;
// varying parts of the strings are in brackets []
// [somebody] has [some
如何在select语句中包含另一列而不使其成为distinct语句的一部分?我尝试在distinct之前设置另一个列名,但没有成功。

我正在尝试渲染Hello模型。因此,我有这样的tables.py:
