Can Python classes have multiple constructors?

Can Python classes have multiple constructors?

In Python, you can't have multiple constructors like in some other languages, but you can achieve similar functionality using default arguments or class methods.

Can you give me an example of how to do that?

Sure! You can use a class method as an alternative constructor. Here's an example:

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

    @classmethod
    def from_polar(cls, r, theta):
        x = r * cos(theta)
        y = r * sin(theta)
        return cls(x, y)

In this example, from_polar acts as an alternative constructor.

What if I want to create an object with only one parameter?

You can set default values for the other parameters in the __init__ method. For example:

point = Point(x=5)

This will create a Point object with x set to 5 and y defaulting to 0.
