will be helpful for those in need You access members of an array by subscripting, then the properties as normal. For example:
code :
let temperaturePreference = arrayOfCustomers[0].temperaturePreference

this one helps. I have made a subclass of NSObject that is meant to be the model of my application. The class has a few methods and on instance primitive array as such: , (1)
code :
int cubeState[5][2][2];
...
    for (int i=0; i<=5; i++) {
        for (int j=0; j<=2; j++) {
            for (int k=0; k<=2; k++) {
- (void)init {
[[[Cube alloc] init] autorelease];
- (id)printContent;

hope this fix your issue I have created a class in Python that has only abstract methods, and then implemented all the methods in the class BasicMR (not all the code of BasicMR is present in the snippet, but the method test_stationary() is called inside self.generate_positions()): , You are calling test_stationary on the class:
code :
>>> BasicMR.test_stationary(42)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 20, in test_stationary
AttributeError: 'int' object has no attribute '_BasicMR__securities'
>>> BasicMR([])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 17, in __init__
  File "<string>", line 6, in generate_positions
NotImplementedError: You must implement generatePositions()!

To fix this issue It turned out that I tried to execute getUrl() method on a nested object, however I didn't included this object in query.

hop of those help? Passing the instance, as Andrey stated, is the recommended way to do it. But another option would be to create a class variable (you do that with two at signs like so: @@class_variable_name). That would be updated across all instances of the class (kind of like a global variable).

I wish did fix the issue. You want to pass self (the instance of Foo being initialized) to Bar and Baz, not the class Foo itself.
code :
class Foo(object):
    a=9
    def __init__(self):
        self.bar = Bar(self)
        self.baz = Baz(self)
