Answer:
class Phone(object):
def __init__(self, features, phones=[]):
self.features = features
self.phones = phones
Explanation:
In python object-oriented programming, an instance variable of a class object is created in the "__init__()" method. the "self" is a convention name used to represent the instance of an object class. The input values are assigned to the object variable with the self.'argument_name' statement.
When the phone argument is not given, the self.phones variable is initialized as an empty list.

Answer:
A light bulb produces light from electricity
Answer:
a. True
Explanation:
The Newton's method (Newton-Raphson method) used in advanced statistical computing can be used for a continuous and differentiable function that can be approximated by a straight line tangent to it. It requires the derivative of the function to be known, Newton's method converges faster that is whenever it converges. Newton Raphson Method has quadratic convergence which is faster, and the quadratic convergence makes the error in the next iteration increase by the square of the value of the previous iteration.
Answer:
overriding is defining a function in derived class with same name which is already exist in base class.
Explanation:
Override key word is used in DotNet for overriding .It differes from language to language.In c++ no keyword is required for overriding.
#include<iostream.h>
public class BaseClass
{
public :
void print(){
cout<<"print in base class";
}
}
public class DerivedClass : public BaseClass
{
public :
void print(){
cout<<"print in derived class";
}
}
void main(){
BaseClass b=new BaseClass();
b.print();
DerivedClass d=new DerivedClass();
d.print()
}
