having list of lists, mylist = [[1, 3, 4], [3, 6, 7], [8, 0, -1, 3]] i need method list containing indexes of elements of value, '3' example. value of '3' such list of indexes should be [[0, 1], [1, 0], [2, 3]] thanks in advance. update : can have several instances of sought-for value ('3' in our case) in same sublist, like my_list = [[1, 3, 4], [3, 6, 7], [8, 0, -1, 3, 3]] so desired output [[0, 1], [1, 0], [2, 3], [2, 4]] . i suppose solution naive, here is: my_list = [[1, 3, 4], [3, 6, 7], [8, 0, -1, 3, 3]] value = 3 list_of_indexes = [] in range(len(my_list)): j in range(len(my_list[i])): if my_list[i][j] == value: index = i, j list_of_indexes.append(index) print list_of_indexes >>[(0, 1), (1, 0), (2, 3), (2, 4)]] it great see more compact solution assuming value appears once in each sublist, use following function, makes use of built in enumerate function , list c...

there several forks of nodejs , of them support javascript engines other google's v8 engine. for node code see js engine running under, best way? the engines aware of are: google's v8 - engine supported official node.js , iojs fork. 1 of engines supported jxcore . mozilla's spidermonkey - 1 of engines supported jxcore . microsoft's chakracore - engine supported microsoft 's port of node.js , apparently 1 of engines supported jxcore though haven't got 1 work yet. ( i've asked separate question detecting fork of nodejs being used. question detecting js engine.) the process object contains lot of information running process (in case, node). my process.versions example, contains current version of v8: process: { versions: { http_parser: '2.5.0', node: '4.2.4', v8: '4.5.103.35', uv: '1.7.5', zlib: '1.2.8', ares: '1.10.1-dev', ...

according cppreference.com , std::thread constructor no parameter means: creates new thread object not represent thread. my questions are: why need constructor? , if create thread using constructor, how can "assign" thread function later? why don't have "run(function_address)" method when constructed no parameter, can specify function "run" thread . or, can construct thread callable parameter (function, functors, etc.) call "run()" method execute thread later. why std::thread not designed in way? your question suggests there might confusion , helpful separate ideas of thread of execution std::thread type, , separate both idea of "thread function". a thread of execution represents flow of control through program, corresponding os thread managed kernel. an object of type std::thread can associated thread of execution , or can "empty" , not refer thread of execution . there no such conc...
