string - Best way to check if a character is a number of letter in javascript? -

in javascript whats best way check if character (length 1), number (i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) or letter (i.e. z, z)? thanks i wrote little test case you, @ least numeric checking function. considering fact functions returns true either numberic 1 or string '1' literal, using array seems fastest way (at least in chrome). var isnumericchar = (function () { var arr = array.apply(null, array(10)).map(function () { return true; }); return function (char) { return !!arr[char]; }; })(); however, if accept might return false 1 , switch statement faster.

Python Lists -Syntax for '[' -

-
i need declare values in list. values looks this: ["compute","controller"], ["compute"] ,["controller"] i know list syntax in python example = [] i not sure how include square brackets , double quotes in list. please help. i tried following: cls.node = ["\["compute"\]","\["controller"\]"] cls.node = ["[\"compute\"]","[\"controller\"]"] both did not work. i think mean list not dictionary because syntax of list : you can using following format '"hello"' : cls.node = ['["compute"]','["controller"]'] cls.node = ['["compute"]','["controller"]'] demo: s = ['["hello"]', '["world"]'] in s: print [output] ["hello"] ["world"]
