double-quotes

问题 I am trying to read a large dataset in .csv format which is update automatically using the pandas library. The problem is that in my data, the first row is a string without double quotation marks, and the other colums are strings with double quotation marks. It is not possible for me to adjust the .csv file manually. A simplified dataset would look like this A,"B","C","D" comp_a,"tree","house","door" comp_b,"truck","red","blue" I need the data to be stored as separate columns without the

问题 This question already has answers here : HTML attribute with/without quotes (6 answers) Closed 5 years ago . I have a .html file and ist .css file. I call the .css trough the instruction <link rel= stylesheet href= mystyle.css> But if I use <link rel= "stylesheet" href= "mystyle.css"> then nothing changes in my page. Is there some difference between using the quotes or not? 回答1: I believe the spec defines it to have quotes, but some browsers go beyond and will know what you meant. EDIT : I

问题 This seems like such an obscure question, but here it goes: Is there a way to concatenate String Literals with a DirectoryInfo enumeration (which contains a file path) while adding quotations around the file path? Further, how can I prevent backslashes from being doubled when converting a DirectoryInfo enumeration to a string? My situation is as follows: DirectoryInfo filePathDirectory = new DirectoryInfo(filePath); Process a = new Process(); a.StartInfo.FileName = "C:\\Windows\\system32\\lpr

问题 I am struggling with parsing values from a CSV file because of two consecutive double quotes "" . Here's an example of a CSV field I pulled from wikipedia: 1997,Ford,E350,"Super, ""luxurious"" truck" I have tried to find different ways to account for it. The result I keep getting is: "1997" "Ford" "E350" "Super," ""Super" " ""luxurious"" truck"" This is my VB.Net function. Private Function splitCSV(ByVal sLine As String) As List(Of String) Dim comA As Integer = -1, comB = -1, quotA = -1,

问题 I am using Microsoft.VisualBasic.FileIO.TextFieldParser to read a csv file, edit it , then parse it. The problem is the quotes are not being kept after parsing. I tried using parser.HasFieldsEnclosedInQuotes = true; but it does not seem to keep the quotes for some reason. This issue breaks when a field contains a quote for example : Before "some, field" After some, field As two seperate fields Here is my method public static void CleanStaffFile() { String path = @"C:\file.csv"; String dpath =

问题 I have a built a system which loads words from a database table but I need to add those words to a list of type "Choices" (the type that is needed for Grammar Building). This is my code for requesting words to be retrieved from the database: List<string> newWords = new List<string>(); newWords = LexicalOperations.WordLibrary().ToList(); Choices dbList = new Choices(); //Adding them to a Choice List if (newWords.Count != 0) { foreach (string word in newWords) { dbList.Add(word.ToString()); } }

问题 I'm currently working with a regular expression (in Javascript) for replacing double quotes with smart quotes: // ie: "quotation" to “quotation” Here's the expression I've used for replacing the double quotes: str = str.replace(/"([A-Za-z ]*)"/ig, "“$1”") The above works perfectly if the phrase inside the quotes contains no additional punctuation, however, I also need to replace any apostrophes: // ie: replace "It's raining again" with “It’s raining again!” The expression for replacing single

问题 I am using a regex to replace quotes within in an input string. My data contains two 'types' of quotes - " and “ There's a very subtle difference between the two. Currently, I am explicitly mentioning both these types in my regex \"*\“* I am afraid though that in future data I may get a different 'type' of quote on which my regex may fail. How many different types of quotes exist? Is there way to normalize these to just one type so that my regex won't break for unseen data? Edit - My input
