key

问题 just a simple problem here. I have the following array: Array(21) { [0] => Array(7) { ["punti"] => Integer 418 ["vittorie"] => Integer 9 ["podi"] => Integer 18 ["gv"] => Integer 14 ["id_pilota"] => Integer 1 ["team"] => String(15) "Red Bull Racing" ["naz"] => String(2) "it" } [1] => Array(7) { ["punti"] => Integer 353 ["vittorie"] => Integer 6 ["podi"] => Integer 16 ["gv"] => Integer 3 ["id_pilota"] => Integer 19 ["team"] => String(16) "Scuderia Ferrari" ["naz"] => String(2) "it" } [2] =>

问题 I have some Entrys in a python list.Each Entry has a creation date and creation time.The values are stored as python datetime.date and datetime.time (as two separate fields).I need to get the list of Entrys sorted sothat previously created Entry comes before the others. I know there is a list.sort() function that accepts a key function.In this case ,do I have to use the date and time to create a datetime and use that as key to sort() ? There is a datetime.datetime.combine(date,time) for this.

问题 In this playground I would like to create a map containing at most a single action of each type in the Action union. Each of the unioned types is differentiated by having a different string literal property 'type'. I have a definition for this map which compiles but is too loose... const lastAction:{ [A in Action["type"]]?:Action } = {} The constraint on keys within the lastAction map enforces that... the key is a "type" property from some Action type the value must be some Action type ...it

问题 Given the following JSON object, using jq, how to get the last two elements for each item? I have been trying to find a solution with the help of jqplay.org but didn't get anywhere. While getting values out of objects having consistent key names is rather straightforward, I can't get my head around this. Input: { "foo": { "abc": { "key1": "value1" }, "bcd": { "key1": "value1" }, "cde": { "key1": "value1" }, "def": { "key1": "value1" }, "efg": { "key1": "value1" }, "fgh": { "key1": "value1" }

问题 consider a file 'b.json': [ { "id": 3, "foo": "cannot be replaced, id isn't in a.json, stay untouched", "baz": "do not touch3" }, { "id": 2, "foo": "should be replaced with 'foo new2'", "baz": "do not touch2" } ] and 'a.json': [ { "id": 2, "foo": "foo new2", "baz": "don't care" } ] I want to update the key "foo" in b.json using jq with the matching value from a.json. It should also work with more than one entry in a.json. Thus the desired output is: [ { "id": 3, "foo": "cannot be replaced, id

问题 I need to update this script to pass my key so that I don't go over the limit per day. How would I modify this script to pass my key? (NOTE: google class information found here: https://developers.google.com/apps-script/reference/maps/geocoder) function geo2zip(a) { var response=Maps.newGeocoder() .reverseGeocode(lat(a),long(a)); return response.results[0].formatted_address.split(',')[2].trim().split(' ')[1]; } function lat(pointa) { var response = Maps.newGeocoder() .geocode(pointa); return

问题 I have the following JSON: { "data": [ { "{#NAME}": "Test 1", "{#ID}": "1", "{#IP}": "192.168.1.2:80" }, { "{#NAME}": "Test 2", "{#ID}": "2", "{#IP}": "" }, { "{#NAME}": "Test 3", "{#ID}": "3", "{#IP}": "192.168.1.3:80" }, { "{#NAME}": "Test 4", "{#ID}": "4", "{#IP}": "192.168.1.4:80" }, { "{#NAME}": "Test 5", "{#ID}": "5", "{#IP}": "" } ] } But I want to return: { "data": [ { "{#NAME}": "Test 1", "{#ID}": "1", "{#IP}": "192.168.1.2" }, { "{#NAME}": "Test 2", "{#ID}": "2", }, { "{#NAME}":

问题 I want to programattically handle the ENTER key in android. Is there any way to achieve this? Please Help!! Thanks in advance 回答1: You need to carefully override the following function: @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { case KeyEvent.KEYCODE_ENTER: { //your Action code return true; } } return super.onKeyDown(keyCode, event); } 回答2: Use onKey() to capture the key. KEYCODE_NUMPAD_ENTER is used for the numeric ENTER key, and KEYCODE_DPAD_CENTER

问题 I'm working with midi note, midi number, and frequency. What kind of list in python should I use to refer to any one attribute and get the other attributes? for example: input: "C3" , return frequency and get 261.6255653006 . input: 261.6255653006 , return midinumber and get 60 input: 60 , return midinote and get "C3" what syntax, functions, objects, or list type would I use? 回答1: Like I said in the comments, a dictionary of tuples is what you're probably looking for. Example: data = {'C3': (

问题 I wanted to know how I can find duplicate values in a dictionary and the return the keys that contain those values. So here is an example: d = {'happy':['sun', 'moon', 'chocolate'], 'sad':['fail', 'test', 'bills'], 'random': ['baloon', 'france', 'sun'] } As you can see the key's happy and random have the same/duplicate value in them, which is 'sun' , so the output I was looking for is: random, happy I cant really understand how I can find duplicate values like that. If I had a particular
