Answer:

List=[['Computers','IT','Programming'],['Maths', 'Algebra', 'Geometry']]

i=0

k=0

for i in range(0,2):

print("Category:"+List[i][0])

for k in range(1,3):

print("\t"+List[i][k])

Explanation:

The required program is as above. We have used here a multidimensional list. The 0 of each row has the category,and rest are sub categories. The program above has limitations but is good enough to explain the fundamentals required.

#Write a function called string_finder. string_finder should #take two parameters: a target string and a search string. #The fun

adoni [48]

Answer:

I am writing a Python program:

def string_finder(target,search): #function that takes two parameters i.e. target string and a search string

position=(target.find(search))# returns lowest index of search if it is found in target string

if position==0: # if value of position is 0 means lowers index

return "Beginning" #the search string in the beginning of target string

elif position== len(target) - len(search): #if position is equal to the difference between lengths of the target and search strings

return "End" # returns end

elif position > 0 and position < len(target) -1: #if value of position is greater than 0 and it is less than length of target -1

return "Middle" #returns middle

else: #if none of above conditions is true return not found

return "not found"

#you can add an elif condition instead of else for not found condition as:

#elif position==-1

#returns "not found"

#tests the data for the following cases

print(string_finder("Georgia Tech", "Georgia"))

print(string_finder("Georgia Tech", "gia"))

print(string_finder("Georgia Tech", "Tech"))

print(string_finder("Georgia Tech", "Idaho"))

Explanation:

The program can also be written in by using string methods.

def string_finder(target,search): #method definition that takes target string and string to be searched

if target.startswith(search): #startswith() method scans the target string and checks if the (substring) search is present at the start of target string

return "Beginning" #if above condition it true return Beginning

elif target.endswith(search): #endswith() method scans the target string and checks if the (substring) search is present at the end of target string

return "End" #if above elif condition it true return End

elif target.find(search) != -1: #find method returns -1 if the search string is not in target string so if find method does not return -1 then it means that the search string is within the target string and two above conditions evaluated to false so search string must be in the middle of target string

return "Middle" #if above elif condition it true return End

else: #if none of the above conditions is true then returns Not Found

return "Not Found"

Which of the following code is correct? I: print("Programming is fun") print("Python") print("Computer Science") II: print("Prog

vfiekz [6]

Answer:

None of the options is correct.

Explanation:

One of the simplest statements that you can write in Python is a print statement, which causes a message to be displayed on the screen. For example, the following statement causes the message Python programming is fun! to be displayed:

print 'Python programming is fun!'

Notice that after the word print, the Python programming is fun! was written inside a set of single-quote marks. The quote marks are necessary, but they will not be displayed. They simply mark the beginning and the end of the text that we wish to display.

Here is an example of how you would type this print statement at the interpreter’s

prompt:

>>> print 'Python programming is fun!'

After typing the statement you press the Enter key and the Python interpreter executes the statement, as shown here:

>>> print 'Python programming is fun!'

Python programming is fun!

>>>

Thus, the correct way to write the codes in the question is:

print 'Programming is fun'

print 'Python'

print 'Computer Science'

An administrator has been working within an organization for over 10 years. He has moved between different IT divisions within t

rodikova [14]

Answer:

User roles and access authorization

(Explanation of this question is given below in the explanation section.

Explanation:

As noted in question that a terminated employee comeback in office and installed some malicious script on a computer that was scheduled to run a logic bomb on the first day of the following month. And, that script will change administrator passwords, delete files, and shut down over 100 servers in the data center.

The following problem can be with that account

Unauthorized user access and privileges

The user may be given unauthorized access to system resources. If a user has unauthorized access to system resource then he can modify or destroy the system function easily.

The firewall may be disabled to detect the malicious script

The firewall should be enabled to detect such types of attack from unauthorized access to the system

Role

May be user role is not defined properly. If role would be defined according to user role then there are very fewer chances in doing unauthorized changes in the system that will result in an unexpected outage.

NeTakaya

Answer:

Explanation:

import java.util.Scanner;

public class KboatTriangleAngle

{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

System.out.print("Enter first angle: ");

int a1 = in.nextInt();

System.out.print("Enter second angle: ");

int a2 = in.nextInt();

System.out.print("Enter third angle: ");

int a3 = in.nextInt();

int angleSum = a1 + a2 + a3;

if (angleSum == 180 && a1 > 0 && a2 > 0 && a3 > 0) {

if (a1 < 90 && a2 < 90 && a3 < 90) {

System.out.println("Acute-angled Triangle");

}

else if (a1 == 90 || a2 == 90 || a3 == 90) {

System.out.println("Right-angled Triangle");

}

else {

System.out.println("Obtuse-angled Triangle");

}

else {

System.out.println("Triangle not possible");

}
