Parameterized Constructor
Parameterized Constructor is a special function which if present automatically gets executed when an object is declared with arguments.
The data elements of the object are initialized by the arguments passed at the time of object declaration
Example:
s=student(101,”Amit”,98.99)
Example:1
Python program to initialize the data elements of the class student using parameterized constructor and display them?
#class creation
class student:
def __init__(self,r,n,p):
self.roll=r
self.name=n
self.per=p
def show(self):
print("Roll no ",self.roll)
print("name ",self.name)
print("Per ",self.per)
#calling
#parameterized
s=student(1001,"Mohan",99.99)
s.show()
Output:
Roll no 1001 name Mohan Per 99.99 >>>
Example:2
Python program to initialize the data elements of the class employee using parameterized constructor and display them?
#class creation
class employee:
def __init__(self,e,n,s):
self.empno=e
self.name=n
self.sal=s
def show(self):
print("Empno ",self.empno)
print("Name ",self.name)
print("Salary ",self.sal)
#calling
#parameterized
e=employee(5001,"Kapil",9800)
e.show()
Output:
Empno 5001 Name Kapil Salary 9800 >>>
