string-parsing

问题 Although there are similar questions, I can't seem to find a working solution for my case: I'm encountering some annoying hex chars in strings, e.g. '\xe2\x80\x9chttp://www.google.com\xe2\x80\x9d blah blah#%#@$^blah' What I need is to remove these hex \xHH characters, and them alone, in order to get the following result: 'http://www.google.com blah blah#%#@$^blah' decoding doesn't help: s.decode('utf8') # u'\u201chttp://www.google.com\u201d blah blah#%#@$^blah' How can I achieve that? 回答1:

问题 How do I parse ANY Number type from a String in Java? I'm aware of the methods like Integer.parseInt(myString) and Double.parseDouble(myString) but what I optimally want is a method like Number.parseNumber(myString) which doesn't exist. How can I achieve that behaviour in another way? (I want the parsed Number to reflect the String "exactly" in terms of for example number of decimals). Example: "0" => Number (internally of Integer subclass) "0.0" => Number (internally of Double subclass) Also

问题 This question already has answers here : How do you get the hue of a #xxxxxx colour? (5 answers) Closed 2 years ago . Hello I'm trying to create HEX to HSL converter function. I know that at first I should convert HEX to RGB and then from RGB to HSL. I've done so using some script from StackOverflow. S and L is working correctly but H (hue) is not. I do not know why, here's my code: toHSL: function(hex) { var result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hex); var r = parseInt

问题 According to the docs for Split, there is a rev method on the result of doing split on a string: fn main() { let mut length = 0; let mut mult = 1; for part in "1:30".split(":").rev() { length += mult * part.parse::<i32>().unwrap(); mult *= 60; } } I get the following error: error[E0277]: the trait bound `std::str::pattern::StrSearcher<'_, '_>: std::str::pattern::DoubleEndedSearcher<'_>` is not satisfied --> src/main.rs:4:35 | 4 | for part in "1:30".split(":").rev() { | ^^^ the trait `std::str
