Getting a dictionary from an object

Hello.

I would like to have a quick way to create dicts from object, so that a
call to foo['bar'] would return obj.bar.

The following works, but I would prefer to use a built-in way if one
exists. Is there one?

Thanks in advance.

class dictobj(dict):
"""
class dictobj(dict):
A dictionary d with an object attached to it,
which treats d['foo'] as d.obj.foo.
"""
def __init__(self, obj):
self.obj = obj
def __getitem__(sel f, key):
return self.obj.__geta ttribute__(key)

I'm not sure what you're getting at, but have you tried this:

class A(object):
def __getitem__(sel f, ky):
return self.__dict__[ky]

for example:
class A(object): def __init__(self,a ,b,c):
self.a = a
self.b = b
self.c = c
def __getitem__(sel f, ky):
return self.__dict__[ky]

a = A(1,2,3)
a['a'] 1 a['b'] 2

Hi, I'm trying to use a generics dictionary with a key class that implements and needs IComparable<>. However when I attempt to use the dictionary, it doesn't appear to use the IComparable<> to find the key. In the example below, accessing the dictionary by using the exact key object that was used to add to the dictionary works. (see code comment 1). However, if I attempt to access the dictionary by using a key object that

I have a dictionary object, then I create a new dictionary object and sets it equal to my original, then I pass the new dictionary object to a function that changes some of my values - but then my original dictionary also gets changed and that was not the intention, can someone explain to me why it behaves that way and how do I avoid it, så I van have different dictionary objects?

I have the following: Dictionary<object, stringd = new Dictionary<object, string>(); I can add entries to the dictionary, and I can loop through the entries I've added to the Dictionary. This all works great. My question is: I'd like to find a way to get just the first key, without looping through the whole Dictionary. I tried the code below, but I get a compile error trying to use an index value on the KeyCollection:

Hi folks, I have a Dictionary which contains a string key and an object value. I want the object value to point to a property in my class and I want it to be by reference, so that later on I can change the value of the property through the dictionary. I am having difficulty making the value be by reference. Is this possible? I've even tried unsuccessfully to use unsafe code with pointers.

hello, I'm trying to use a dictionary as a class member. I want to use a property to get/set the key/value of the dictionary but I'm confused as how to use a dictionary as a property. Since there are 2 parts, I don't know how to setup the get/sets. I tried searching but could not find any examples. I'd appreciate an example of how to get/ set the two parts of a dictionary via a property of a class. tia
