Python Modules
Python ModulesNitin Reddy Katkam Python modules allow code reuse and organization. A module is a Python file with a .py extension that contains functions and other objects. Modules can be imported and their contents accessed using dot notation. Modules have a __name__ variable that is set to the module name when imported but is set to "__main__" when the file is executed as a script. Packages are collections of modules organized into directories, with each directory being a package. The Python path defines locations where modules can be found during imports.

Chapter 07 inheritance
Chapter 07 inheritancePraveen M Jigajinni 1. Inheritance is a mechanism where a new class is derived from an existing class, known as the base or parent class. The derived class inherits properties and methods from the parent class.
2. There are 5 types of inheritance: single, multilevel, multiple, hierarchical, and hybrid. Multiple inheritance allows a class to inherit from more than one parent class.
3. Overriding allows a subclass to replace or extend a method defined in the parent class, while still calling the parent method using the super() function or parent class name. This allows the subclass to provide a specific implementation of a method.
Basics of Object Oriented Programming in Python
Basics of Object Oriented Programming in PythonSujith Kumar The document discusses key concepts of object-oriented programming (OOP) including classes, objects, methods, encapsulation, inheritance, and polymorphism. It provides examples of classes in Python and explains OOP principles like defining classes with the class keyword, using self to reference object attributes and methods, and inheriting from base classes. The document also describes operator overloading in Python to allow operators to have different meanings based on the object types.
Python-Classes.pptx
Python-Classes.pptxKarudaiyar Ganapathy Object-oriented programming (OOP) organizes code around data objects rather than functions. In Python, classes are user-defined templates for objects that contain attributes (data) and methods (functions). When a class is instantiated, an object is created with its own copies of the attributes. Self refers to the object itself and allows methods to access and modify its attributes. Classes in Python allow for code reusability, modularity, and flexibility through encapsulation, inheritance, and polymorphism.
Python programming : Classes objects
Python programming : Classes objectsEmertxe Information Technologies Pvt Ltd A class is a code template for creating objects. Objects have member variables and have behaviour associated with them. In python a class is created by the keyword class.
An object is created using the constructor of the class. This object will then be called the instance of the class.
Python exception handling
Python exception handlingMohammed Sikander Exception handling in Python allows programmers to handle errors and exceptions that occur during runtime. The try/except block handles exceptions, with code in the try block executing normally and code in the except block executing if an exception occurs. Finally blocks ensure code is always executed after a try/except block. Programmers can define custom exceptions and raise exceptions using the raise statement.
Class, object and inheritance in python
Class, object and inheritance in pythonSantosh Verma The document discusses object-oriented programming concepts in Python, including classes, objects, methods, inheritance, and the built-in __init__ method. Classes are created using the class keyword and contain attributes and methods. Methods must have a self parameter, which refers to the instance of the class. The __init__ method is similar to a constructor and is called when an object is instantiated. Inheritance allows one class to inherit attributes and methods from another class.

Python-Encapsulation.pptx
Python-Encapsulation.pptxKarudaiyar Ganapathy Encapsulation involves bundling data members and functions inside a class to help with data hiding and ensure objects work independently. It wraps both data and methods into a single unit so end-users only need to provide inputs and receive outputs. Encapsulation provides well-defined, readable code; prevents accidental modification; and provides security. Python supports public, private, and protected access modifiers to restrict access to variables and functions within and outside classes.

Python : Data Types
Python : Data TypesEmertxe Information Technologies Pvt Ltd All data values in Python are encapsulated in relevant object classes. Everything in Python is an object and every object has an identity, a type, and a value. Like another object-oriented language such as Java or C++, there are several data types which are built into Python. Extension modules which are written in C, Java, or other languages can define additional types.
To determine a variable's type in Python you can use the type() function. The value of some objects can be changed. Objects whose value can be changed are called mutable and objects whose value is unchangeable (once they are created) are called immutable.

From Java to Python: beating the Stockholm syndrome
From Java to Python: beating the Stockholm syndromeJavier Arias Losada Java and Python are compared on various aspects such as verbosity, object orientation, and execution model.
Python is found to be more concise and readable than Java for many common tasks like file I/O and logical expressions. However, Java's static typing enables safer refactoring. Both support inheritance but Python allows multiple inheritance and "duck typing".
The execution model differs as well - in Python, code is executed as it is loaded while Java separates loading, initialization and execution. This makes features like monkey patching possible in Python.
In the end, the developer is more important than the language. While each has strengths, the presenter currently prefers Python for its pragmatism and conciseness.

five-minute-change of the index, our combined mathematical model of an auto regression (AR) and a
neural network (NN) is proposed.In the experimental results, the combined model showedthe root mean
square error (RMSE) of 0.23 degrees, in comparison with 0.37 and 0.26 for conventional single NN and AR
models, respectively. This result is satisfactory prediction for required comfort of approximately 1 degree
Celsius allowance.

CLASS OBJECT AND INHERITANCE IN PYTHON
- 1. CLASS OBJECT & INHERITANCE I N P Y T H O N
- 2. CONTENTS Class Object Inheritance
- 3. WHAT ARE CLASSES AND OBJECTS IN PYTHON? Python is an object oriented programming language. Unlike procedure oriented programming, where the main emphasis is on functions, object oriented programming stress on objects. Object is simply a collection of data (variables) and methods (functions) that act on those data. And, class is a blueprint for the object. We can think of class as a sketch (prototype) of a house. It contains all the details about the floors, doors, windows etc. Based on these descriptions we build the house. House is the object. As, many houses can be made from a description, we can create many objects from a class. An object is also called an instance of a class and the process of creating this object is called instantiation.
- 4. DEFINING A CLASS IN PYTHON Like function definitions begin with the keyword def, in Python, we define a class using the keyword class. Here is a simple class definition.
- 5. CREATING AN OBJECT IN PYTHON We saw that the class object could be used to access different attributes. It can also be used to create new object instances (instantiation) of that class. The procedure to create an object is similar to a function call.
- 6. EXAMPLE
- 8. WHAT IS INHERITANCE? Inheritance is a powerful feature in object oriented programming. It refers to defining a new class with little or no modification to an existing class. The new class is called derived (or child) class and the one from which it inherits is called the base (or parent) class.
- 10. TYPES OF INHERITANCE Single Inheritance Multiple Inheritance Multilevel Inheritance Hybrid Inheritance Hierarchical Inheritance
- 11. SINGLE INHERITANCE In which there is one base class and one derived class
- 12. MULTIPLE INHERITANCE Multiple inheritance is possible in python A class can be derived from more then one base classes. The syntax for multiple inheritance is similar to single inheritance Here is an example of multiple inheritance
- 14. MULTILEVEL INHERITANCE Multilevel inheritance is also possible in Python like other Object Oriented programming languages. We can inherit a derived class from another derived class, this process is known as multilevel inheritance. In Python, multilevel inheritance can be done at any depth.
- 18. HIERARCHICAL INHERITANCE In which there is single base class and multiple derived class
