constructor in class in python by R4R Team

__init__() is the function which work as a constructor when we build any class.

Syntax-

def __init__(self,variables):
body


program-

#create class
class Computer():
def __init__(self):
print("Object is created")

#create object
c1=Computer()
c2=Computer()

output-

Object is created
Object is created

-In this program, initially we create a class named as 'Computer' that contain constructor named as __init__()
-So when we create an object by c1=Computer() then this function automatically call and print 'Object is created' and similarly other object works.

Pass argument in constructor-

program-

#create class
class Computer():
def __init__(self,name,age):
print("Name is ",name)
print("Age is ",age)

#create object
c1=Computer('John wick',89)
c2=Computer('Tony strak',45)

output-

Name is John wick
Age is 89
Name is Tony strak
Age is 45
