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?
In Python, there is no existence of Private methods that cannot be accessed except inside a class. However, to define a private method prefix the member name with the double underscore “__”. Note: The __init__ method is a constructor and runs as soon as an object of a class is instantiated.
In the python method and constructor, overloading is not possible.
The constructor is a method that is called when an object is created. This method is defined in the class and can be used to initialize basic variables. If you create four objects, the class constructor is called four times. Every class has a constructor, but its not required to explicitly define it.
It is executed automatically whenever an object of a class is created. The only restriction that applies to the constructor is that it must not have a return type or void. It is because the constructor is automatically called by the compiler and it is normally used to INITIALIZE VALUES.
class MyClass(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.
