Alloc: Class method of NSObject. Returns a new instance of the receiving class. Init: Instance method of NSObject. Implemented by subclasses to initialize a new object (the receiver) immediately after memory for it has been allocated. New: Class method of NSObject. Allocates a new instance of the receiving class, sends it an init message, and … Read more
-init is an instance method, used to initialize a particular object. +initialize is a class method, run before any instances of the class are created and before other class methods are run. +initialize isn’t something you use most of the time, but it’s handy for setting up any static variables that the class as a … Read more
Your commands look correct (I’ve done them many times that way). First try git add –all and then try git status. I don’t think that will solve it, but worth trying next. Next try looking at your .gitignore file, if you have one (in the top level where you did git init). cat .gitignore Remove … Read more
super(SubClass, self).__init__(…) Consider using *args and **kw if it helps solving your variable nightmare.
JavaScript doesn’t have a built-in init() function, that is, it’s not a part of the language. But it’s not uncommon (in a lot of languages) for individual programmers to create their own init() function for initialisation stuff. A particular init() function may be used to initialise the whole webpage, in which case it would probably … Read more
In the first situation, Num2 is extending the class Num and since you are not redefining the special method named __init__() in Num2, it gets inherited from Num. When a class defines an __init__() method, class instantiation automatically invokes __init__() for the newly-created class instance. In the second situation, since you are redefining __init__() in … Read more
You should be able to put them in __init__.py. This is done all the time. mypackage/__init__.py: MY_CONSTANT = 42 mypackage/mymodule.py: from mypackage import MY_CONSTANT print “my constant is”, MY_CONSTANT Then, import mymodule: >>> from mypackage import mymodule my constant is 42 Still, if you do have constants, it would be reasonable (best practices, probably) to … Read more
The first is used to initialise newly created object, and receives arguments used to do that: class Foo: def __init__(self, a, b, c): # … x = Foo(1, 2, 3) # __init__ The second implements function call operator. class Foo: def __call__(self, a, b, c): # … x = Foo() x(1, 2, 3) # __call__
I think you mean git add . which will add all of the files to the repo that AREN’T specified in the .gitignore – you can see these changes by typing git status The . in bash usually means this directory and all other directories recursively, so if you do this from the bottom level … Read more
Why would you want to do that? If you want to return some other object when a class is called, then use the __new__() method: class MyClass(object): def __init__(self): print “never called in this case” def __new__(cls): return 42 obj = MyClass() print obj
