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’]; 0 solved PHP Multidimensional Array Access
Solution for Jackson: Declare serializer for specific class Pair public static class PairSerializer extends StdSerializer<Pair> { public PairSerializer() { this(null); } public PairSerializer(Class<Pair> t) { super(t); } @Override public void serialize(Pair value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonProcessingException { jgen.writeStartObject(); jgen.writeObjectField(“a”, value.getFirst()); // “a” is replacement for “first” jgen.writeObjectField(“b”, value.getSecond()); // “b” is replacement … Read more
You could do this: a = {‘vladimirputin’: {‘milk’: 2.87, ‘parsley’: 1.33, ‘bread’: 0.66}, ‘barakobama’:{‘parsley’: 0.76, ‘sugar’: 1.98, ‘crisps’: 1.09, ‘potatoes’: 2.67, ‘cereal’: 9.21}} b = {} for prez in a: for food in a[prez]: if food not in b: b[food] = {prez: a[prez][food]} else: b[food][prez] = a[prez][food] This gives: {‘bread’: {‘vladimirputin’: 0.66}, ‘cereal’: {‘barakobama’: 9.21}, … Read more
Try this // file path $file=”orderdata.txt”; // REMEMBER TO MENTION THE CORRECT FILE WITH EXTENSION // open the file and get the resource handle with errors suppressed $handle = @fopen($file,’r’); // DONT USE @ while at development since it will suppress errors // array to hold our values $params = array(); if($handle) { // if … Read more
Trick The trick is to find out in advance whether a target_key is among the next children (= this_dict[key] = the values of the current dict iteration) before you reach the child level recursively. Only then you can still delete a key:value pair of the child level while iterating over a dictionary. Once you have … Read more
my_dict = {key1:{value1:value2}, key2:{value3:value4}, key3{value5:value6}, key4:{value7:value8}…} result = [] for key1 in my_dict: if sum(my_dict[key1].keys() + my_dict[key1].values())==3: result[key1] = my_dict[key1].keys()[0] Hope this helps solved Python – selectively add up values while iterating through dictionary of dictionaries [closed]
