What is the preferred way to write Python doc string? """ or " In the book Dive Into Python , the author provides the following example: def buildConnectionString(params): """Build a connection string from a dictionary of parameters. Returns string.""" In another chapter , the author provides another example: def stripnulls(data): "strip whitespace and nulls" return data.replace("\00", "").strip() Both syntax work. The only difference to me is that """ allows us to write multi-line doc. Is there any difference other than that? From the PEP8 Style Guide : PEP 257 describes good docstring

I'm trying to create a search and replace string like this: src=\"/path/file.jpg\" into src=\"http://mysite.com/path/file.jpg\" By searching for the property src and the equals slash quote. The problem is creating the search string, every time I do it, it becomes a search for src=\\"/ instead of src=\"/ if property = "src" in this segment, how can I get it to work? string equalsSlashQuote = "=" + @"\" + "\""; string search = property + equalsSlashQuote + "/"; string replace = property + equalsSlashQuote + SiteURL + "/"; input = input.Replace(search, replace); The problem is the \, I even tried

In chapter 3 of Practical Common Lisp book there's an example of a SQL-like select and where functions. Here's a simplified version of it: (defun where (x) #'(lambda (item) (> item x))) and it is used like this: (remove-if-not (where 2) (list 1 2 3 4)) Earlier in the book it is explained that the #' sequence is used to state that it is followed by a function name, rather than a variable that requires evaluation. I don't understand why it's needed here. I tried implementing the where function without it and it worked as well: (defun where (x) (lambda (item) (> item x))) I tried googling for it,

What is the difference between (cons 2 3) and '(2 . 3) in Lisp? '(2 . 3) is a dotted pair. (cons 2 3) creates a dotted pair too. So these should evaluate to the same thing. So one is a literal for a dotted pair, the other one creates a dotted pair. They are not exactly the same, even though they evaluate to the same values in the REPL. Consider these examples, in which cons cells are modified destructively: TEST> (defun literal-cons () (let ((cons '(1 . 2))) (incf (cdr cons)) cons)) LITERAL-CONS TEST> (literal-cons) (1 . 3) TEST> (literal-cons) (1 . 4) TEST> (literal-cons) (1 . 5) Compared to

I have an application, and it is fed some HTML. It then needs to put that HTML into a string. This HTML contains single and double quotes. Is it possible, in javascript, to declare a string with information inside of it, that does not use single or double quotes? Thanks, and I guess if it is not possible, does anyone know a simple and easy way to escape these quotes so I can put it in a string? Keep in mind, part of this string will be javascript that I will later need to execute. Thanks! You need to escape the quotation characters with \ : var someString = 'escape all the quotation marks \"\'
