Inheritance in Python
• Inheritance allows us to reuse code written for a base class • Inheritance becomes di?cult when the diamond pattern is allowed: • What happens if parents share a method with the same name • What if one parent overwrites a grandfather method and the other one does not Grandfather Parent1 Parent2 Child
Object-Oriented Programming in Python: inheritance - uniboit
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

What is inheritance in Python?
- This tutorial will go through some of the major aspects of inheritance in Python, including how parent classes and child classes work, how to override methods and attributes, how to use the super() function, and how to make use of multiple inheritance. What Is Inheritance? Inheritance is when a class uses code constructed within another class.
What is inheritance in biology?
- Inheritance is when a class uses code constructed within another class. If we think of inheritance in terms of biology, we can think of a child inheriting certain traits from their parent. That is, a child can inherit a parent’s height or eye color. Children also may share the same last name with their parents.
What were the major changes in Python 3?
- The focus of Python 3 development was to clean up the codebase and remove redundancy, making it clear that there was only one way to perform a given task. Major modi?cations to Python 3.0 included changing the print statement into a built-in function, improve the way integers are divided, and providing more Unicode support.
What is Python 3?
- Python 3 is the most current version of the language and is considered to be the future of Python. This tutorial will guide you through installing Python 3 on your local macOS machine and setting up a programming environment via the command line. Prerequisites

Zen of Python
20 software principles that influence the design of Python:
1Beautiful is better than ugly.2Explicit is better than implicit.3Simple is better than complex.4Complex is better than complicated.5Flat is better than nested.6Sparse is better than dense.7Readability counts.8Special cases aren"t special enough to break the rules.9Although practicality beats purity.10Errors should never pass silently.11Unless explicitly silenced.12...

Is Python fast enough?
For user programs: Python is fast enough!
Most parts of Python are written in C
For compute intensive algorithms: Fortran, C, C++ might be better Performance-critical parts can be re-implemented in C/C++ if necessaryFirst analyse, then optimise!

Strong and Dynamic Typing
Strong Typing:Object is of exactly one type! A string is always a string, an integer always an integer
Counterexamples: PHP, JavaScript, C:charcan be interpreted asshort,void *can be everythingDynamic Typing:No variable declaration
Variable names can be assigned to different data types in the course of a program An object"s attributes are checked only at run timeDuck typing
(an object is defined b yits methods and attr ibutes) When I see a bird that walks like a duck and swims like a duck and quacks like a duck, I call that bird a duck.22 James Whitcomb RileyMember of the Helmholtz AssociationSlide 10
Example: Strong and Dynamic Typing
