Default constructor in Python with example

  • by

The Python default constructor is a simple constructor which doesn’t accept any arguments. Its definition has only one argument which is a reference to the instance being constructed.

def __init__(self):
    # body of the constructor

A constructor is a method with always has a name init and the name init is prefixed and suffixed with a double underscore(__). It’s declared a constructor using def keywords, just like methods.

Example Default constructor in Python

The constructors are to initialize/ assign values to the data members of the class when an object of the class is created.

class Test:

    # default constructor
    def __init__(self):
        self.msg = "Default constructor"

    # a method for printing data members
    def display(self):

# creating object
obj = Test()
