Constructors In Python

I need help in writing code for a Python constructor method. This constructor method would take the following three parameters: x, y, angle What is an example of this?

Solution 1:

classMyClass(object):def__init__(self, x, y, angle):
    self.x = x
    self.y = y
    self.angle = angle

The constructor is always written as a function called __init__(). It must always take as its first argument a reference to the instance being constructed. This is typically called self. The rest of the arguments are up to the programmer.

The object on the first line is the superclass, i.e. this says that MyClass is a subclass of object. This is normal for Python class definitions.

You access fields (members) of the instance using the self. syntax.

Solution 2:

Constructors are declared with __init__(self, other parameters), so in this case:

def__init__(self, x, y, angle):
    self.x = x
    self.y = y
    self.angle = angle

You can read more about this here: Class definition in python

Solution 3:

See the Python tutorial.

Solution 4:

class MyClass(SuperClass):
    def __init__(self, *args, **kwargs):
        super(MyClass, self).__init__(*args, **kwargs)
        # do initialization
