I have a crufty old DNS provisioning system that I'm rewriting and I hope improving in python. (It's based on tinydns if you know what that is.) The record formats are, in the worst case, like this: foo.[DOM]::[IP6::4361:6368:6574]:600:: What I would like to do is to split this string into a li

Re: Quote-aware string splitting

Quoted strings are surprisingly stateful, so that using a parser isn't totally out of line. Here is a pyparsing example with some added test cases. Pyparsing's quotedString built-in handles single or double quotes (if you don't want to be this permissive, there are also sglQuotedString and dblQuo

Quote-aware string splitting

Hello, I need to split a string as per string.strip(), but with a modification: I want it to recognize quoted strings and return them as one list item, regardless of any whitespace within the quoted string. For example, given the string: 'spam "the life of brian" 42' I'd want it to return: ['spa
