what is mouse and how many types of mouse are there​

Answer:

Here is the Python code:

runs=int(input("how many runs do you want to add items to dictionary? "))  #store input number of runs

d = dict()  #creates a dictionary

d = {0:10,1:20}  #old dictionary

count=0  #counts number of runs

for x in range(2,runs+2):  #loop to append key/value pairs to dictionary

   d[x]=(x*10)+10  #multiples and adds 10 to the each value

   count+=1  #adds 1 to the count at each iteration

   print("After the #",count, "run the new dictionary is: ",d) #prints the new dictionary

Explanation:

I will explain the program with an example:

The old dictionary is :

d = {0:10,1:20}  

runs = 3

count = 0

At first iteration:

x = 2

d[x]=(x*10)+10

This becomes:

d[2]=(2*10)+10

d[2]= 20 + 10

d[2]= 30

count+=1

count = 1

   print("After the #",count, "run the new dictionary is: ",d)

This statement displays the first iteration result :

After the # 1 run the new dictionary is:  {0: 10, 1: 20, 2: 30}  

At  second iteration:                                                              

x = 3

d[3]=(3*10)+10

This becomes:

d[3]=(3*10)+10

d[3]= 30 + 10

d[3]= 40

count+=1

count = 2

   print("After the #",count, "run the new dictionary is: ",d)

This statement displays the first iteration result :

After the # 2 run the new dictionary is:  {0: 10, 1: 20, 2: 30, 3: 40}      

At  third iteration:                                                              

x = 4

d[4]=(4*10)+10

This becomes:

d[4]=(4*10)+10

d[4]= 40 + 10

d[4]= 40

count+=1

count = 3

   print("After the #",count, "run the new dictionary is: ",d)

This statement displays the first iteration result :

After the # 3 run the new dictionary is:  {0: 10, 1: 20, 2: 30, 3: 40, 4: 50}    

Now the loop breaks as x = 5 necause n+2 = 3+2 = 5 limit is reached

Answer:

Explanation:

This is a significant need because the teacher's/manufacturer's specifications are created so that the individual operating the equipment knows how to properly operate it. Failure to read and properly interpret these specifications can lead to the damaging of the equipment, damaging the food, contamination of the food, and even injury/death to the operator. That is why it is crucial that the information is read and interpreted correctly as well as implemented as instructed.

There's a need to properly interpret teacher's/manufacturer's specifications before operating any food processing equipment due to D. All of these.

From the information given, it should be noted that there's a need to properly interpret teacher's/manufacturer's specifications before operating any food processing equipment in order to be familiar with the parts and functions.

Also, it's important in order to avoid accidents due to faulty operation of equipment and to be able to determine the correct operation of the equipment. Therefore, the correct operation is all of the above.

Answer:

Here is the Python program:

arrow_base_height = int(input('Enter arrow base height: \n'))  #prompts user to enter the arrow base height

arrow_base_width = int(input('Enter arrow base width: \n')) #prompts user to enter the arrow base width

arrow_head_width = int(input('Enter arrow head width: \n'))  #prompts user to enter the arrow head width

while (arrow_head_width <= arrow_base_width):  #ensures that the arrow head width is greater than base width

    arrow_head_width = int(input('Enter arrow head width: \n'))  #keeps prompting user to enter arrow head width until the value is larger than the arrow base width.

for i in range(arrow_base_height):  #to print arrow shaft

   for j in range(arrow_base_width):  #iterates through arrow base width

       print ('*', end='')  #prints asterisks

   print ()  #prints new line

for i in range(arrow_head_width):  #iterates through arrow head width arrow head

   for j in range(arrow_head_width-i):  #iterates through arrow head width-i

        print ('*', end='')  #prints asterisks

   print()  #prints new line

Explanation:    

The program works as follows:

Suppose user enters 5 as arrow base height, 2 as arrow base width and 4 as arrow head widths so,

arrow_base_height = 5

arrow_base_width = 2

arrow_head_width = 4

Since the arrow_head_width is not less than arrow_base_width so the while loop at the start does not execute. Program control moves to the statement:

for i in range(arrow_base_height):

for j in range(arrow_base_width):

Both of these loop are used to print the shaft line and after execution of these loops the output becomes:

**

**

**

**

**

Note that the outer loop is executed 5 times as arrow_base_height=5 and the inner loop iterates two times for each iteration of outer loop because arrow_base_width is 2 and the print ('*', end='') statement keeps printing the asterisks whereas print() prints a new line after printing 2 asterisks at each line.

Next the program moves to the following loops:

for i in range(arrow_head_width):

   for j in range(arrow_head_width-i):

Both of these loop are used to print the arrow head and after execution of these loops the output becomes:

****

***

**

*

Note that the outer loop is executed 4 times as arrow_head_width=4 and the inner loop iterates 4 times in start and decrements one time at each iteration and the print ('*', end='') statement keeps printing the asterisks whereas print() prints a new line after printing 2 asterisks at each line.

So the entire output of this program is:

**

**

Explanation:

In this question, the server uses special port 21 and  20 for the command and data transfer. A customer uses a random short-term N > 1023 and N+1 ports Listen and the Ports may be randomly distributed and the following samples are given for:  

In point (a):

X: 1030 Client, W server: 21 (service)  

W: 20 server (data) ,Client X:1031

In point (b):

Server W: 21 (command) Client Y: 1035  

Client Y: 1036, (data) Server W: 20  

In point (c):

Client X: 1030, Server W: 21.  

Client X: 1031, (data) Server W: 20  

In point (d):

Client X: 1035, Server W: 21.  

Client X: 1036 ,(data): Server W: 20.  

In point (e):

Yes, it's an opportunity. It can be the same as a certain likelihood.  

In point (f):

The port of the server is the norm. If W and Y are on the same host, the client's port numbers can vary.
