I need to determine if an unknown 5 or 6 letter string is a valid word, i.e. is in the dictionary. I could submit the string/word to an online dictionary, but I need to check this string/word, which will be different each time, for about 100 to 150 times. This seems to be a bit time consuming. My next thought would be to try to get a di...
Here is a twofold question, with a theoretical part, and a practical one: When subclassing dict: class ImageDB(dict): def __init__(self, directory): dict.__init__(self) # Necessary?? ... should dict.__init__(self) be called, just as a "safety" measure (e.g., in case there are some non-trivial implementation deta...
I'm currently implementing a complex microbial food-web in Python using SciPy.integrate.ode. I need the ability to easily add species and reactions to the system, so I have to code up something quite general. My scheme looks something like this: class Reaction(object): def __init__(self): #stuff common to all reactions d...
What's the best way to transform an IEnumerable into a lookup- or dictionary-like structure, but with multiple keys per value? What I'm looking for is something that does roughly the same thing as this, and in a generic way: var wordsByLetter = new Dictionary<char, HashSet<string>>(); foreach (string word in words) { foreach (char l...

Hello all. I have the following code that I think should work - however, what I think and what actually works is something completely different! This being demonstrated by the fact it doesn't work! protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { Dictionary<String, String> headerTooltips = new ...
I am building a class which subclasses dict, and overrides __setitem__. I would like to be certain that my method will be called in all instances where dictionary items could possibly be set. I have discovered three situations where Python (in this case, 2.6.4) does not call my overridden __setitem__ method when setting values, and inst...
I've always used dictionaries. I write in Python. ...
What is the most efficient method to store a Python dictionary on the disk? The only methods I know of right now are plain-text and the pickle module. Edit: Sorry for not being very clear. By efficient I meant fastest execution speed. The dictionary will contain mutable objects that will hold information to be parsed and modified. ...
Hi. I am new to iphone development. I am "old School" - I was tought to use Procedures etc. when programming. Everything is object oriented these days but my style is still as its always been. Please bear that in mind. My project is tiny and really just a proof of concept. The program below works on a timer - every 30 seconds it will r...

edit: Thanks Jason, the fact that it was a dictionary isn't that important. I just wanted the runtime to have a low runtime. Is that LINQ method fast? Also, I know this is off topic but what does the n => n mean? I have a list of numbers and I want to make another list with the numbers that appear most at the beginning and the least...
Hello. I am working on an iPhone app that will construct, at run-time, an NSMutableDictionary for which the values (of the key-value pairs) will be NSMutableArrays. Being somewhat new to the Objective-C, I am concerned that the following will cause a memory leak: - (void) addNewSupplierPhoto:(UIImage*)image toSupplierID:(NSInteger*) sup...

The resultant dictionary would...

It is pre-filled with most models of car. I want to find any match for any row in my models table. So if I have Civic, Mustang and E350 in my ...
If I have a deeply nested dict is there a built-in way to subtract/remove list of "paths" (eg: keyA.keyB.key1, keyA.keyC.key2, etc) or a the keys of a second dict from the original dict? Or maybe there is a common module which has functionality like this? ...
Hi, I want to create a data store to allow me to store some data. The first idea was to create a dictionary where you have 1 key with many values, so a bit like a one to many relationship I think the dictionary only has 1 key value. How else could I store this information?? Marc ...
