• Subclassing Cocoa means no subclass ivars in some cases?

  - by Michael

  The question is generally coming from self = [super init]. In case if I'm subclassing NSSomething and in my init's method self = [super init] returns object of different class, does it mean I am not able to have my very own ivars in my subclass, just because self will be pointing to different class? Appreciate if you could bring some examples if my statement is wrong.

• Convert list of dicts to string

  - by John

  I'm very new to Python, so forgive me if this is easier than it seems to me. I'm being presented with a list of dicts as follows: [{'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}, {'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}, {'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}] I would like to generate a simple string of memberIds, such as [email protected], [email protected], [email protected] but every method of converting a list to a string that I have tried fails because dicts are involved. Any advice?
