Question

#python. Explain code script of each part using comments for the reader. The code script must work without any errors or bugs.
Ball moves in a 2D coordinate system beginning from the original point (0,0). The ball can
move upwards, downwards, left and right using x and y coordinates. Code must ask the
user for the destination (x2, y2) coordinate point by using the input x2 and y2 and the known
current location, code can use the euclidean distance formula to work out the distance
to the destination. Code should repeatedly ask the user to input the destination
coordinates to shift the ball further but, once the user types the value 999, the code
should print all previous movements of the ball by showing the distance of each step. Also trace function
prints the total distance travelled by the ball.

Please find below the code, code screenshots and output screenshots. Please refer to the screenshot of the code to understand the indentation of the code.  Please get back to me if you need any change in code. Else please upvote

CODE:

import math

x_cordinates = [0] #Declare list to store the x cordinates and initialize it with starting x cordinate 0

y_cordinates = [0] #Declare list to store the y cordinates and initialize it with starting y cordinate 0

while True: #Loop continuously

    x = int(input("\nEnter the destination x coordinate to shift the ball: ")) #Reading the x cordinate of destination

    if(x == 999): #If the value entered is 999, break the loop

        break

    y = int(input("Enter the destination y coordinate to shift the ball: ")) #Reading the y cordinate of destination

    if(y == 999): #If the value entered is 999, break the loop

        break

    x_cordinates.append(x) #Adding the x cordinate to list x_cordinates

    y_cordinates.append(y) #Adding the y cordinate to list y_cordinates

print("\nSource   Destination     Distance") #Displaying table header

for i in range(len(x_cordinates) - 1): #Loop through each index in list

    #getting the current x and y cordinates to x1 and y1

    x1 = x_cordinates[i]

    y1 = y_cordinates[i]

    #getting the next x and y cordinates to x2 and y2

    x2 = x_cordinates[i+1]

    y2 = y_cordinates[i+1]

   

    distance = math.sqrt( ((x1-x2)**2)+((y1-y2)**2)) #Calculating the distance between the two points

   

    print("({:d},{:d})    ({:d}, {:d}) {:>15.2f}".format(x1, y1, x2, y2, distance)) #Displaying the cordinates and distance
