Python is a completely object-oriented language. You have been working with classes and objects right from the beginning of these tutorials. Every element in a Python program is an object of a class. A number, string, list, dictionary, etc., used in a program is an object of a correspond...
The value list filter can also be used for Boolean data types. For Boolean data types, this filter contains two values: true and false. These value are used inPythonfor specifying the value. The true value is the first value in the list. For an example, seeAdd Fieldand the...
If the handler returns objects that can't be serialized byjson.dumps, the runtime returns an error. If the handler returnsNone, as Python functions without areturnstatement implicitly do, the runtime returnsnull. If you use theEventinvocation type (anasynchronous invocation), the value is disca...

Every object-oriented programming language must acquire some features like inheritance, use of class & objects, polymorphism, encapsulation, data abstraction. These features make the differentiation between a procedural and an object-oriented language. High-level languages like Java and Python allow...
