I promised in an earlier module that I would revisit and explain the difference between class variables and instance variables in classes and objects. An earlier module explained instance variables in detail. You will learn some of the details regarding class variables in this module.
Table of contents
Preface
This module is one in a collection of modules on Python designed for
teaching
ITSE 1359 Introduction to Scripting Languages: Python at Austin Community
College in Austin, TX.
What you have learned
Earlier modules provided
- an overview of classes and objects in Python,
- an explanation of the
self word in Python class definitions,
and
- a detailed explanation of instance variables in Python class
definitions.
You have also learned that although other OO languages such as Java and C++use terminology that is common with Python terminology, such as
class ,
object ,
class variable , and
instance variable , those
terms have significantly different meanings in Python than they do in many otherOO languages.
What you will learn
I promised in an earlier module that I would revisit and explain the
difference between
class variables and
instance variables in
classes and objects. An earlier module explained instance variables in detail.You will learn some of the details regarding class variables in this module.
Viewing tip
I recommend that you open another copy of this module in a separate
browser window and use the following links to easily find and view the Figuresand the Listings while you are reading about them.
(Note to blind and visually impaired students: most of the Figures and all of the
Listings inthis module are presented in plain text format and should be accessible using an
audio screen reader or a braille display. Note however that the requiredindentation may not be properly represented by an audio screen reader.)

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

how do you save a country economic situation when it's falling apart
what is the difference between economic growth and development
Economic growth as an increase in the production and consumption of goods and services within an economy.but
Economic development as a broader concept that encompasses not only economic growth but also social & human well being.

What do you think is more important to focus on when considering inequality ?
any question about economics?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏
Asui
it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
