Answer:

The program in Python is as follows:

fname = input("Enter the translation file name: ")

with open(fname) as file_in:

lines = []

for line in file_in:

lines.append(line.rstrip('\n'))

myDict = {}

for i in range(len(lines)):

x = lines[i].split(":")

myDict[x[0].lower()] = x[1].lower()

print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")

word = input("Enter an English word: ")

while(True):

if not word:

break

if word.lower() in myDict:

print("The Spanish word is ",myDict[word.lower()])

else:

print("I don’t have that word in my list.")

word = input("Enter an English word: ")

Explanation:

This prompts the user for file name

fname = input("Enter the translation file name: ")

This opens the file for read operation

with open(fname) as file_in:

This creates an empty list

lines = []

This reads through the lines of the file

for line in file_in:

This appends each line as an element of the list

lines.append(line.rstrip('\n'))

This creates an empty dictionaty

myDict = {}

This iterates through the list

for i in range(len(lines)):

This splits each list element by :

x = lines[i].split(":")

This populates the dictionary with the list elements

myDict[x[0].lower()] = x[1].lower()

This prints an instruction on how to use the program

print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")

This prompts the user for an English word

word = input("Enter an English word: ")

This loop is repeated until the user presses the ENTER key

while(True):

If user presses the ENTER key

if not word:

The loop is exited

break

If otherwise, this checks if the word exists in the dictionary

if word.lower() in myDict:

If yes, this prints the Spanish translation

print("The Spanish word is ",myDict[word.lower()])

If otherwise,

else:

Print word does not exist

print("I don’t have that word in my list.")

Prompt the user for another word

word = input("Enter an English word: ")

This function receives first_name and last_name, then prints a formatted string of "Name: last_name, first_name" if both names a

pishuonlain [190]

Answer:

Following are the program in the C++ Programming Language.

//set header file

#include <iostream>

//set namespace

using namespace std;

//define class

class format

{

//set access modifier

public:

//set string type variable

string res;

//define function

void names(string first_name, string last_name)

{

//set if-else if condition to check following conditions

if(first_name.length()>0 && last_name.length()>0)

{

res="Name: "+last_name+", "+first_name;

}

else if(first_name.length()>0 and last_name.length()==0)

{

res="Name: "+first_name;

}

else if(first_name.length()==0 and last_name.length()==0)

{

res="";

}

//define function to print result

void out(){

cout<<res<<endl;

}

};

//define main method

int main() {

//set objects of the class

format ob,ob1,ob2;

//call functions through 1st object

ob.names("John","Morris");

ob.out();

//call functions through 2nd object

ob1.names("Jhon","");

ob1.out();

//call functions through 3rd object

ob2.names("", "");

ob2.out();

}

<u>Output</u>:

Name: Morris, John

Name: Jhon

Explanation:

<u>Following are the description of the program</u>:

Define class "format" and inside the class we define two void data type function.

Define void data type function "names()" and pass two string data type arguments in its parameter "first_name" and "last_name" then, set the if-else conditional statement to check that if the variable 'first_name' is greater than 0 and 'last_name' is also greater than 0 then, the string "Name" and the following variables added to the variable "res". Then, set else if to check that if the variable 'first_name' is greater than 0 and 'last_name' is equal to 0 then, the string "Name" and the following variable "first_name" added to the variable "res".
Define void data type function "out()" to print the results of the variable "res".

Finally, we define main method to pass values and call that functions.

You are helping a friend in college with his network connection. He would like a high speed connection between his computers so

inna [77]

Solution :

Set up the router as follows:

On the Shelf, expand the Routers. And read the description for each of the devices. Drag the Ethernet $100/1000TX$ router with the firewall to the Workspace.

Connection of the router as follows:

Above the router, select the Back to switch to the back view of the router. Then select the cable currently connected to the wall plate and then drag it to a $LAN$ port on the router. Above the Dorm- $PC2$ computer, select $\text{back}$ to switch to the back view of the computer. On the Shelf, expand Cables. Select a Cat5e $RJ45$ cable. In the Selected Component window, drag the connector to the $LAN$ port on the computer. In the Selected Component window, drag the other connector to a $LAN$ port on the router. Select a Cat5e $RJ45$ cable. In the Selected Component window, drag a connector to the $WAN$ port on the router. In the Selected Component window, drag the other connector to the port on the wall plate.

Provide power to the router as follows:

On the Shelf, select the power adapter. In the Selected Component window, drag the DC power connector to the power port on the router. In the Selected Component window, drag the AC adapter connector to the surge protector. Above the router, select Front to switch to the front view to verify power and network activity lights.

Request new $TCP/IP$ information from the router for Dorm-PC as follows:

On the $\text{Dorm-PC}$ monitor, select Click to view $\text{Windows 10}$ .In the Search field on the taskbar, enter command prompt. Under Best Match, select Command Prompt. Enter $\text{ipconfig}$ /renew and press $\text{Enter}$ to request new $TCP/IP$ information from the router. In the notification area, right-click the Network icon and select Open Network and Sharing Center. The network information map should indicate an active connection to the Firewall Network and the internet.

Configure Windows Firewall on $\text{Dorm-PC}$ as follows:

In Network and Sharing, select Windows Firewall. From the left menu, select Turn Windows Firewall on or off. Under Private network settings, select Turn on Windows Firewall. Under Public network settings, select Turn on Windows Firewall. Click OK.

Write a function sample_median(n,P) that generates n random values using distribution P and returns the median of the collected

TiliK225 [7]

Answer:

import numpy as np

def sample_median(n, P):

return np.median( np.random.choice ( np.arange (1, len(P) + 1 ), n, p = P ) )

print(sample_median(10,[0.1 0.2 0.1 0.3 0.1 0.2]))

print(sample_median(5, [0.3,0.7])

Explanation:

Bring in the numpy library to use the median function provided by the numpy library.
Define the sample_median function that takes in 2 parameters and returns the median with the help of built-in random, choice and arrange functions.
Call the sample_median function by providing some values to test and then display the results.
