Is there any way to create an empty constructor in python. I have a class:
class Point: def __init__(self, x, y, z): self.x = x self.y = y self.z = z now I initialize it like this:
p = Point(0, 5, 10) How can I create an empty constructor and initialize it like this:
p = Point()

This is because there is a default constructor implicitly injected by python during program compilation, this is an empty default constructor that looks like this: def __init__(self): # no body, does nothing. In this case, python does not create a constructor in our program.
In Python the __init__() method is called the constructor and is always called when an object is created. Types of constructors : default constructor: The default constructor is a simple constructor which doesn't accept any arguments.
You should define the __init__() method of your Point class with optional parameters. This is the best answer. It covers all of the ground that the original question asks about.
"__init__" is a reserved method in python classes. It is known as a constructor in OOP concepts. This method called when an object is created from the class and it allows the class to initialize the attributes of a class.
class Point: def __init__(self): pass If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
