key-value

Say I have a multidimensional array in PHP such as: this_array= array( string_name=>'string', string_array=>array( 'string_key'=>'string_val' ) ) How am I to access string_array's key-val pairs? Is it just: this_array['string_array']['string_key'] Or is it something different? David Code should look something like this, if you were intending on using strings as your keys. $this_array= array( 'string_name' => 'string', 'string_array' => array( 'string_key' => 'string_val' ) ); Yes, you will access it by: $this_array['string_array']['string_key']; 来源： https://stackoverflow.com/questions/10707272

I would like to fetch the string mentioned in 'Value' for various parameter available under 'Name' using c#. Here is my current xml as follows: <DrWatson> <Sets> <Set> <APIParameters> <Parameter Name="SID_STAGE" Value="101198" Required="true" /> <Parameter Name="SID_QE" Value="Test 91817" Required="true" /> </APIParameters> </Set> </Sets> </DrWatson> I would like to fetch the '101198' available under 'Value' for Name = SID_STAGE . Please suggest how can i perform it. You can parse parameters dictionary (that is natural way to store key-value pairs) with LINQ to XML: var xdoc = XDocument.Load

I am trying to make a dictionary from this file: with the key being the first word, and the values being all words afterwards. andrew fred fred judy andrew fred george judy andrew john george This is the code I have: follows_file = open("C:\\Users\\Desktop\\Python\\follows.txt") followers = {} for line in follows_file: #==> [Judy Andrew Fred] users = line.split(' ') #==> [Judy, andrew, Fred, ....] follower = users[0] #==> [Judy] followed_by = users[1:] #==> [Andrew, Fred] for user in followed_by: # Add the 'follower to the list of followers user if user not in followers: followers[user] = []

I have a question related to python code. I need to aggregate if the key = kv1, how can I do that? input='num=123-456-7890&kv=1&kv2=12&kv3=0' result={} for pair in input.split('&'): (key,value) = pair.split('=') if key in 'kv1': print value result[key] += int(value) print result['kv1'] Thanks a lot!! I'm assuming you meant key == 'kv1' and also the kv within input was meant to be kv1 and that result is an empty dict that doesn't need result[key] += int(value) just result[key] = int(value) input = 'num=123-456-7890&kv1=1&kv2=12&kv3=0' keys = {k: v for k, v in [i.split('=') for i in input.split(

I am trying to find the value of a given key from a nested OrderedDict. Key points: I don't know how deep this dict will be nested The name of the key I am looking for is constant, it will be somewhere in the dict I would like to return the value of the key called "powerpoint_color" in this example... mydict= OrderedDict([('KYS_Q1AA_YouthSportsTrustSportParents_P', OrderedDict([('KYS_Q1AA', OrderedDict([('chart_layout', '3'), ('client_name', 'Sport Parents (Regrouped)'), ('sort_order', 'asending'), ('chart_type', 'pie'), ('powerpoint_color', 'blue'), ('crossbreak', 'Total')]))])), My initial

I have written the below code to find out the key(String) that has the maximum value(Integer) using TreeMap in JAVA. public static void maxprofitItem(int[] costs, int[] prices, int[] sales,String[] items) { TreeMap<String,Integer>map=new TreeMap<String,Integer>(); int[] profits=new int[items.length]; int maxvalue; for(int i=0;i<items.length;i++){ profits[i]=sales[i]*prices[i]-costs[i]*sales[i]; if(profits[i]>0){ map.put(items[i],profits[i]); } } Set setOfKeys = map.keySet(); Iterator iterator = setOfKeys.iterator(); while (iterator.hasNext()) { String key = (String) iterator.next(); Integer
