we can convert the dictionary to kw using **kw but if I want kw as str(kw) not str(dict), as I want a string with keyword arguments for code_generator, if I pass obj.method(name='name', test='test', relation = [('id','=',1)]) I want a function to return the string like "name='name', test='test', relation = [('id','=',1)]" ...
I've got the a class created in code an added it to my class diagram. The class diagram is used by a text template generatorto generate code from this class diagram. I'm trying to map a dictionary to an sql database with NHibernate, the generated mapping looks ok to me, but the class property as shown below is giving me problems. This i...
Hi everyone I load from a txt file many info, and I would like, if possible, to dynamically create NSmutable dictionary with the elements of the txt. For example, each is like that: id of element | date | text What I'm asking is the equivalent of the NSString stringWithFormat:. Can we do the same for an Mutable Dictionary? To be more...
I'm trying to get the key of the maximum value in the Dictionary<string, double> results. This is what I have so far: double max = results.Max(kvp => kvp.Value); return results.Where(kvp => kvp.Value == max).Select(kvp => kvp.Key).First(); However, since this seems a little inefficient, I was wondering whether there was a better way ...
How do I sort a keyvalue pair with descending order of their values? foreach (KeyValuePair<string, int> item in keyvalue.OrderBy(key => key.Value)) { } ...
Dictionary<string, int> testdic = new Dictionary<string, int>(); testdic.Add("cat", 1); testdic.Add("dog", 2); testdic.Add("rat", 3); testdic.Remove("cat"); testdic.Add("bob", 4); Fill the dictionary and then remove the first element. Then add a new element. Bob then appears at position 1 instead of at the end, therefore it seems to ...
Hi I am trying to compare 2 Dictionary objects for equality in MbUnit 3.1 like so Assert.AreEqual<FieldList>(expectedOutputFieldList, actualOutputFieldList); Where FieldList is = Dictionary<string, object> However this throws up the following "error": Both values look the same when formatted but they are distinct instances. Is the...
I have two dictionaries with the same structure: Dictionary<string, int> foo = new Dictionary<string, int>() { {"Table", 5 }, {"Chair", 3 }, {"Couch", 1 } }; Dictionary<string, int> bar = new Dictionary<string, int>() { {"Table", 4 }, {"Chair", 7 }, {"Couch", 8 } }; I'd like to sum the values of the dictiona...
I was wondering if there was a dictionary containing string versions of wxPython class (like 'Button' for wx.Button) to the events they call. This is what I want: {'Button': wx.EVT_BUTTON, ...}. Is there a dictionary like this anywhere in the module or on the web? ...
Suppose I have a Dictionary<String,String>, and I want to produce a string representation of it. The "stone tools" way of doing it would be: private static string DictionaryToString(Dictionary<String,String> hash) { var list = new List<String> (); foreach (var kvp in hash) { list.Add(kvp.Key + ":" + kvp.Value); ...
I am having this piece of code, which in my opinion is fairly ugly and I am wondering how it can be done better: if dic.get(key, None) is None: dic[key] = None Points for elegance ;-) ...
Hi, After processing a dictionary of words I have edit distances (or rather similarity in percent) saved in a data structure, kinda like this: s1=String1, s2=String2, similarity=82 s1=String2, s2=String3, similarity=82 s1=aaaaaaa, s2=aaaaaab, similarity=90 s1=aaaaaaa, s2=aaaaaac, similarity=95 My aim is to have a list of groups of simi...
Hi, Weird question, but I have a dictionary created with StringComparer.OrdinalIgnoreCase, looks something like this AaA, 10 aAB, 20 AAC, 12 I then use myDictionary["AAA"] to find the value associated with the key, but what I also need to know is what the actual spelling of the key is in myDictionary, e.g. in this case I want it to re...
Hi guys! So, I have a dictionary with almost 100,000 (key, values) pairs and the majority of the keys map to the same values. For example imagine something like that: mydict = {'a': 1, 'c': 2, 'b': 1, 'e': 2, 'd': 3, 'h': 1, 'j': 3} What I want to do, is to reverse the dictionary so that each value in mydict is going to be a key at ...
I have a System.Collections.Generic.Dictionary<string, string> containing control ID and appropriate data column to data bind: var dic = new Dictionary<string, string> { { "Label1", "FooCount" }, { "Label2", "BarCount" } }; I use it that way: protected void FormView1_DataBound(object sender, EventArgs e) { var row = ((Dat...

Hello Everybody, I have a list of values and I want to put them in a dictionary that would map each value to it's index. I can do it this way: >>> t = (5,6,7) >>> d = dict(zip(t, range(len(t)))) >>> d {5: 0, 6: 1, 7: 2} this is not bad, but I'm looking for something more elegant. I've come across the following, but it does the opp...
I have a particular case where using compound dictionary keys would make a task easier. I have a working solution, but feel it is inelegant. How would you do it? context = { 'database': { 'port': 9990, 'users': ['number2', 'dr_evil'] }, 'admins': ['[email protected]', '[email protected]'], 'domain....
Hi, I have a dictionary of points, say: >>> points={'a':(3,4), 'b':(1,2), 'c':(5,5), 'd':(3,3)} I want to create a new dictionary with all the points whose x and y value is smaller than 5, i.e. points 'a', 'b' and 'd'. According to the the book, each dictionary has the items() function, which returns a list of (key, pair) tuple: >...
