What are some examples of constructor overloading in Python?

In Python, constructor overloading isn't directly supported like in some other languages, but you can achieve similar behavior using default arguments or variable-length arguments. For example, you can define a class with a constructor that takes different numbers of parameters.

Can you show me a code example?

Sure! Here's a simple example:

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

    def display(self):
        print(f'Point({self.x}, {self.y}')

# Creating points with different constructors
p1 = Point()  # Default constructor
p2 = Point(5)  # One argument
p3 = Point(5, 10)  # Two arguments

p1.display()
p2.display()
p3.display()

What if I want to handle more complex initialization?

For more complex initialization, you can use class methods or static methods to create different constructors. Here's an example using a class method:

class Circle:
    def __init__(self, radius):
        self.radius = radius

    @classmethod
    def from_diameter(cls, diameter):
        return cls(diameter / 2)

# Creating a Circle using the class method
c1 = Circle(5)
c2 = Circle.from_diameter(10)
