Unfortunately, like others have said, the Google Dictionary API is deprecated. As I needed a Google Dictionary API for my project, I decided to create one. I scraped the web page for the URL https://www.google.com/#q=define+term where term is any word you want to get meaning of, and created the API. You can find it here. … Read more
Here are the characteristic differences of some important Map implementations: LinkedHashMap: “with predictable iteration order […] which is normally the order in which keys were inserted into the map (insertion-order).” HashMap: “makes no guarantees as to the order of the map” TreeMap: “is sorted according to the natural ordering of its keys, or by a … Read more
This does the job: stats = { ‘copied’: 5, ‘skipped’: 14 } print( ‘Copied: {copied}, Skipped: {skipped}’.format( **stats ) ) #use ** to “unpack” a dictionary For more info please refer to: http://docs.python.org/py3k/library/string.html#format-examples and http://docs.python.org/py3k/tutorial/controlflow.html#keyword-arguments
Dictionary.Clear() will remove all of the KeyValue pairs within the dictionary. Doing new Dictionary() will create a new instance of the dictionary. If, and only if, the old version of the dictionary is not rooted by another reference, creating a new dictionary will make the entire dictionary, and it’s contents (which are not rooted elsewhere) … Read more
Here’s a quick example class Example { private Dictionary<int,string> _map; public Dictionary<int,string> Map { get { return _map; } } public Example() { _map = new Dictionary<int,string>(); } } Some use cases var e = new Example(); e.Map[42] = “The Answer”;
Copying one map to another can be done with operator = or the copy constructor. E.g map<X, Y> mp1; //fill mp1 with data map<X, Y> mp2(mp1); //mp2 is a copy of mp1 (via copy-construction) map<X, Y> mp3; mp3 = mp2; // mp3 is also a copy of mp2 (via copy-assignment)
File.WriteAllLines(“myfile.txt”, dictionary.Select(x => “[” + x.Key + ” ” + x.Value + “]”).ToArray()); (And if you’re using .NET4 then you can omit the final ToArray call.)
Say you have a bunch of students with names and student IDs. If you put them in a List, the only way to find the student with student_id = 300 is to look at each element of the list, one at a time, until you find the right student. With a Map, you associate each … Read more
One way to keep track of instances is with a class variable: class A(object): instances = [] def __init__(self, foo): self.foo = foo A.instances.append(self) At the end of the program, you can create your dict like this: foo_vars = {id(instance): instance.foo for instance in A.instances} There is only one list: >>> a = A(1) >>> … Read more
Or, in LINQ, it’s nice and quick: var _priceDataArray = from row in _priceData select new { Item = row.Key, Price = row.Value }; That should then be bindable, to the columns ‘Item’ and ‘Price’. To use it as a data source in a grid view, you just have to follow it with ToArray(). dataGridView1.DataSource … Read more
