Objects are mutable We can change the state of an object by making an assignment to one of its attributes. For example, to change the size of a rectangle without changing its position, you can modify the values of width and height: box.width = box.width + 50box.height= box.height + ...

Tuple in python is basically like arrays in other languages like Java. 30th Nov 2016, 3:23 PM Resurektzz7 + 3 A tuple is a sequence of objects. It's similar to a list, but tuples are immutable, so you cannot change the values of the objects inside a tuple, as you can do in...
Note:For more details about Python callable objects, check outThe standard type hierarchyin the Python documentation and scroll down to “Callable types.” To create a decorator, you just need to define a callable (a function, method, or class) that accepts a function object as an argument,...
We have seenbeforethat there are differences between mutable and immutable types in Python. Built-in immutable types have always a hash method, while mutable types don't. However, this leaves outside custom defined classes. By default, all instances of custom classes will have a hash value def...
