CONSTRUCTOR IN PYTHON

It is a special kind of method which executes automatically whenever we create object (i.e. without calling it). Contructors are used to initialize the non-static variables of the class at the time of creation of object with the user defined value.

Example –

class A:
    def __init__(self):
        print 'in const of A'
A1=A()

Output –

in const of A

Example –

class A:
    def __init__(self,i,j):
        self.i=i
        self.j=j
A1=A(10,12.12)
print A1.i
print A1.j
A2=A(500,21.25)
print A2.i
print A2.j

Output –

10

12.12

500

21.25
