Which answer would it be?

<h2>My Answer:</h2>

FTP: The definition on Wikipedia is; "The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network."

So, if the question is asking for technology that provides a method for two computers hooked to the internet transfer files back and forth between each other, so if we can sum it up the answer which makes the most sense is <em>FTP</em>.

Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the avera

aliya0001 [1]

Answer:

In python:

file = open("rates.csv", "r")

ratecount = 0

ratesum = 0

mylist = []

rates = file.readlines()

for nums in rates:

num = nums.rstrip('\n')

mylist.append(int(num))

for i in num:

ratesum= ratesum + int(i)

ratecount = ratecount + 1

print("Maximum Rate: "+str(max(mylist)))

print("Minimum Rate: "+str(min(mylist)))

print("Average Rate: "+str(ratesum/ratecount))

Explanation:

This opens the csv file

file = open("rates.csv", "r")

This initializes the number of rates in the file

ratecount = 0

This initializes the sum of the rates

ratesum = 0

This initializes an empty list

mylist = []

This reads the rates into lines

rates = file.readlines()

This iterates through the rates (as a string)

for nums in rates:

This removes the newline character \n in the rates

num = nums.rstrip('\n')

This appends the rates (as an integer) to the empty list

mylist.append(int(num))

The following counts the rates in the file and also sum them up

<em> ratesum= ratesum + int(i) </em>

<em> ratecount = ratecount + 1 </em>

This prints the maximum of the rates

print("Maximum Rate: "+str(max(mylist)))

This prints the minimum of the rates

print("Minimum Rate: "+str(min(mylist)))

This calculates and prints the average rate

print("Average Rate: "+str(ratesum/ratecount))

Explain the concepts o f polymorphism, Encapsulation, Inheritance in detail with suitable examples?

levacccp [35]

Answer:

Encapsulation:-It is the binding of the data and functions so that they works as one unit.

Inheritance:-When one class acquires the property of another class it is called inheritance.

Polymorphism :-It generally means more than one form

Explanation:

Encapsulation:- class is an example of encapsulation it can hold different data types and functions in a single container called class.

class Name{

public:

string first_name;

string last_name;

void Display()

{

cout<<first_name<<" "<<last_name<<endl;

}

};

Inheritance:-The property of a class acquiring the properties of another class is called inheritance.

Now we will inherit the above defined class.

class person: public Name

{

public:

char gender;

int age;

void Display()

{

cout<<first_name<<" "<<last_name<<gender<<age<<endl;

}

};

int main()

{

Name n;

person p;

n.Display();

p.Display();

}

Polymorphism- There are two types of polymorphism:-

1.Run time polymorphism=The values are decided at run time.

2.Compile time polymorphism=The values are decided at compile time.

Example:-In the above example we have function Display() in both the classes.This is an example of compile-time polymorphism. We are deciding at the time of compilation which display to use.
