String.prototype.append = function (str) { return this.concat(str); } end = this.length - 1; } return this.substring(0, start) + this.substring(end +1 , this.length); var regEx = /[^\u4e00-\u9fa5\uf900-\ufa2d]/g; var oMatches = this.match(/[\x00-\xff]/g);

I need help to generate regex so that it will match any string which has following detail correct: String should end with bracket and only numbers inside it. End bracket should appear only once at the end of line and not any where else. Any characters are allowed before bracket start; No characters are allowed after bracket end means: "start-of-string", followed by one s, and immediately followed by "end-of-string". This would therefore only match the string that consists of the single letter s . While technically this is a string starting and ending with s , it is not what you are looking for. 2012-04-01 · If I change {0,2} to {1,1} it produces the correct matches (with e being second character of middle string).

And yes, as Ron mentioned, your suggestion of surrounding the RegEx with \b is important as we don't want the matches surrounded by, say, bEast or Westerly. Thanks, Nam Only the end of the string matches the regex pattern so there’s only one substitution. Again, you can use the re.MULTILINE flag to match the end of each line with the dollar-sign operator: >>> re.sub('Python$', 'Code', 'Is Python Python', flags=re.MULTILINE) 'Is Code Code' Now, you replace both appearances of the string ‘Python’.
