Python Constructor is a part of Object-Oriented Programming in Python which is a special kind of method/function. It is used to intialize instance members of that class.
It is also used to ensure that we have enough resources. If we want to create an object of that class , then constructor definition is the first to execute.
Constructor are used for instantiating an object.Its task is to assign values to the data member of a particular class when the object of that class is created.
__init__() method is called constructor and is called when an object is created.
Here Constructor Overloading means more than one constructor is present in a class with the same name but with a different arguments.
In Python Construction Overloading is not supported:
Example:
In this example we will see that if we give it more than one constructor, that does not do constructor overloading in Python.
class abc:
def __init__(self):
print("Hello World")
def __init__(self):
print("Welcome to Python")
a=abc()
Output: Welcome to Python
In this example, we have used default arguments to overload a constructor.
class abc:
def __init__(self, nam=None):
if nam:
print("Hello", nam)
else:
print("Default Constructor")
obj1 =abc("John")
obj2 =abc()
Output:
Hello John Default Constructor
