Sometimes, we want to implement multiple constructors with Python.
In this article, we’ll look at how to implement multiple constructors with Python.
How to implement multiple constructors with Python?
To implement multiple constructors with Python, we can add class methods into our class that calls the constructor.
For instance, we write
class Cheese(object):
def __init__(self, num_holes=0):
self.number_of_holes = num_holes
@classmethod
def random(cls):
return cls(randint(0, 100))
@classmethod
def slightly_holey(cls):
return cls(randint(0, 33))
@classmethod
def very_holey(cls):
return cls(randint(66, 100))
gouda = Cheese()
havarti = Cheese.random()
to create the Cheese class with the __init__ method.
Then we can create static methods that calls __init__ with different arguments.
Next, we have
gouda = Cheese()
havarti = Cheese.random()
to use the different methods to create Cheese objects.
Conclusion
To implement multiple constructors with Python, we can add class methods into our class that calls the constructor.
