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()

class Point:
    def __init__(self):
        pass

As @jonrsharpe said in comments, you can use the default arguments.

class Point:
    def __init__(self, x=0, y=0, z=0):
        self.x = x
        self.y = y
        self.z = z

Now you can call Point()

You can achieve your desired results by constructing the class in a slightly different manner.

class Point:
    def __init__(self):
        pass

    def setvalues(self, x, y, z):
        self.x = x
        self.y = y
        self.z = z
