What is Attribute in Python

In OOP (Object-Oriented Programming) language, every object has its internal characteristics data called fields, attributes, or properties. In Python, these object-bound characteristics data are generally known as attributes.

1. Class Attributes

In Python, classes are objects. It means that classes can have their own attributes.

class student:
	name = "Jessy"
	age = 15
	grade = 7

print(student.name)

print(student.age)

Output:

Jessy
15

Here name, age, grade are the attributes of the class student. Since these attributes are defined at the class level, they are known as class attributes. They are directly retrievable by the class.

2. Instance Attributes

In classes, we can set attributes to instance objects. These attributes are known as instance attributes. These are instance-specific data. They cannot be shared among objects.

class student:
	name = "Jessy"
	age = 15
	grade = 7

	def __init__(self, score, place):
		self.score = score
		self.place = place
st = student(99, "Agra")

print(st.place)
print(st.score)

 The __init__ function will serve as the construction method to create a new student instance. The first argument self refers to the instance that we’re creating. During the creating the new instance, we will assign the score and place information to the new instance object, and these attributes will become part of the instance’s characteristics.
