What is the difference between this:
Myclass *object = new Myclass(); and
Myclass object = new Myclass(); I have seen that a lot of C++ libraries like wxWidgets, OGRE etc use the first method... Why?

To instantiate a class in Python, the class like it is called a function, passing the arguments defined by the __init__ method. The newly created object is the return value.
Note: The phrase "instantiating a class" means the same thing as "creating an object." When you create an object, you are creating an "instance" of a class, therefore "instantiating" a class. The new operator requires a single, postfix argument: a call to a constructor.
Instantiate in Java means to call a constructor of a Class which creates an an instance or object, of the type of that Class. Instantiation allocates the initial memory for the object and returns a reference.
When you provide a specific example to illustrate an idea, you instantiate it. You say you believe in unicorns, but so far you haven't been able to instantiate that belief.
Myclass *object = new Myclass(); //object has dynamic storage duration (usually is on the heap) Myclass object; //object has automatic storage duration (usually is on the stack) You create objects with dynamic storage duration (usually on the heap) if you plan on using them throughout a long period of time and you create objects with automatic storage duration (usually on the stack) for a short lifetime (or scope).
