Class vs Instance Variables

1️⃣ Class Variable

A class variable is shared by all objects (instances) of the class.

class Student:
    school = "ABC School"   # Class variable

Every student has access to the same school value.

2️⃣ Instance Variable

An instance variable belongs to a specific object.

Usually, it is created inside __init__() using self.

class Student:
    school = "ABC School"   # Class variable

    def __init__(self, name):
        self.name = name     # Instance variable

Now:

s1 = Student("Tisha")
s2 = Student("Rahul")

print(s1.name) #Tisha
print(s2.name) #Rahul
print(s1.school) #ABC School
print(s2.school) #ABC School
