Try writing the properties as a comma separated list, then split the value after the properties file is loaded. For example a=one,two,three b=nine,ten,fourteen You can also use org.apache.commons.configuration and change the value delimiter using the AbstractConfiguration.setListDelimiter(char) method if you’re using comma in your values.
There is an API for bringing up the built-in dictionary UI (not the original question but raised in some of the responses), including checking for whether a given word is defined: if ([UIReferenceLibraryViewController dictionaryHasDefinitionForTerm:@”word”]) { UIReferenceLibraryViewController* ref = [[UIReferenceLibraryViewController alloc] initWithTerm:@”word”]; [currentViewController presentViewController:ref animated:YES completion:nil]; }
A very common pattern to do this is to use an empty dict as your default: d.get(‘foo’, {}).get(‘bar’) If you have more than a couple of keys, you could use reduce (note that in Python 3 reduce must be imported: from functools import reduce) to apply the operation multiple times reduce(lambda c, k: c.get(k, {}), … Read more
You can use JSTL <c:forEach> tag to iterate over arrays, collections and maps. In case of arrays and collections, every iteration the var will give you just the currently iterated item right away. <%@ taglib prefix=”c” uri=”http://java.sun.com/jsp/jstl/core” %> <c:forEach items=”${collectionOrArray}” var=”item”> Item = ${item}<br> </c:forEach> In case of maps, every iteration the var will give … Read more
Assuming that data is some object and that you want to put its public properties into a Dictionary then you could try: Original – here for historical reasons (2012): Dictionary<string, string> FD = (from x in data.GetType().GetProperties() select x) .ToDictionary (x => x.Name, x => (x.GetGetMethod().Invoke (data, null) == null ? “” : x.GetGetMethod().Invoke (data, … Read more
Why don’t you just create a new one? lang = {‘en’: lang[‘en’]} Edit: Benchmark between mine and jimifiki’s solution: $ python -m timeit “lang = {‘ar’:’arabic’, ‘ur’:’urdu’,’en’:’english’}; en_value = lang[‘en’]; lang.clear(); lang[‘en’] = en_value” 1000000 loops, best of 3: 0.369 usec per loop $ python -m timeit “lang = {‘ar’:’arabic’, ‘ur’:’urdu’,’en’:’english’}; lang = {‘en’: lang[‘en’]}” … Read more
How about this: >>> [x for x in data2 if x not in data1] [{‘name’: u’String 3′}] Edit: If you need symmetric difference you can use : >>> [x for x in data1 + data2 if x not in data1 or x not in data2] or >>> [x for x in data1 if x not … Read more
I personally find methods like cata that take two closures as arguments are often overdoing it. Do you really gain in readability over map + getOrElse? Think of a newcomer to your code: What will they make of opt cata { x => x + 1, 0 } Do you really think this is clearer … Read more
On Python 3, use dct.keys() to get a dictionary view object, which lets you do set operations on just the keys: >>> for sharedkey in dct1.keys() & dct2.keys(): # intersection of two dictionaries … print(dct1[sharedkey], dct2[sharedkey]) In Python 2.7, you’d use dct.viewkeys() for that. In Python 2, dct.keys() returns a list, a copy of the … Read more
If you are searching by the fieldname1 value, try this: var r = exitDictionary .Select(i => i.Value).Cast<Dictionary<string, object>>() .Where(d => d.ContainsKey(“fieldname1”)) .Select(d => d[“fieldname1”]).Cast<List<Dictionary<string, string>>>() .SelectMany(d1 => d1 .Where(d => d.ContainsKey(“valueTitle”)) .Select(d => d[“valueTitle”]) .Where(v => v != null)).ToList(); If you are looking by the type of the value in the subDictionary (Dictionary<string, object> explicitly), … Read more
