Using Python to write a program that displays a square using the function DisplaySquare(n, ch). The function receives n as a parameter for the length of the square, and ch as a character used in the display For example,  DisplaySquare(5,’#’) will display the following pattern on screen: ##### ##### ##### ##### #####

Write a python application to simulate an Online Book Shop. Notes: Option 1 and Option 2 must display the list of books to the user.  The Main function accounts for invalid options. Program displays error message for invalid user option, invalid ISBN number or any invalid title.The programmer can create the book title, price, and ISBN information for the books. Each item consists only one string of comma-separated data: book ISBN number, title, and price. A customer can purchase some books either by ISBN number and/or by title. If the user input an invalid number or book title, the program should display an error message. The user can stop shopping with “checkout” option , which triggers the checkout() function that computes the total cost of the books in the cart. A customer will be provided the following menu option while shopping at the book shop: Option 1. Purchase by ISBN: User can purchase a book by its ISBN number. ISBN stands for International Standard Book Number. This is a…

Description Dot Product Task: Write a program that outputs the dot product of two given vectors. Your program should read the vectors from command line arguments, convert them to integers, output the vectors, and finally compute and output the resulting dot product. Let V and U be two vectors, where |V| we run the program as $ python dotproduct.py 156724 then the two vectors are V = [1, 5, 6] U = [7, 2, 4] and their dot product is calculated by V • U = (1 × 7) + (5 * 2) + (6 × 4) Example $ python dotproduct.py 1 23321 V = { 1, 2, 3 } U = {3, 2, 1 } V. U = 10 = ||U|= = 3 (the size of both vectors will always be 3). If

Ruby Programming:  Write a function that takes a number x as a parameter and returns the value of x3 Test the function for values x= 2 and x= 3. Output should be 8 and 27 respectively.

In computer animation, a "jiffy" is commonly defined as 1/100th of a second. Define a function named jiffies_to_seconds that takes the number of "jiffies" as a parameter, and returns the number of seconds. Then, write a main program that reads the number of jiffies (float) as an input, calls function jiffies_to_seconds() with the input as argument, and outputs the number of seconds. Output each floating-point value with three digits after the decimal point, which can be achieved as follows: print (f'{your_value:.3f}') Ex: If the input is: 15.25 the output is: 0.152 The program must define and call the following function: def jiffies_to_seconds (user_jiffies) 461710.3116374.qx3zqy7 LAB ACTIVITY 7.11.1: LAB: A jiffy 1 # Define your function here 12345 3 if __name__ main.py == '__main__': # Type your code here. Your code must call the function. 0/10 Load default template...

in python “c” represents a crop and “w” represents a water source. Each water source hydrates the eight tiles around it (including itself) Input the number of rows and columns in the crop field:ROWS> 4COLUMNS> 4Input each row of the crop field.ROW0> c c c wROW1> w c c cROW2> c c c cROW3> c w c cNot all crops are watered!OUTPUT FalseThe following crops are not watered:OUTPUT [(2, 3), (3, 3)]   Input the number of rows and columns in the crop field:ROWS> 7COLUMNS> 1Input each row of the crop field.ROW0> cROW1> wROW2> cROW3> cROW4> wROW5> cROW6> wAll crops are watered!OUTPUT True

Develop a program that allows the user to enter a start value of 1 to 4, a stop value of 5 to 12 and a multiplier of 2 to 8.  The program must display a multiplication table with results using these values.  For example, if the user enters a start value of 3, a stop value of 7 and a multiplier value of 3, the table should be displayed as follows: Multiplication Table 3 x 3 = 9 3 x 4 = 12 3 x 5 = 15 3 x 6 = 18 3 x 7 = 21 additionally  Each multiplication problem must be displayed with a problem number. The program must prompt the user to enter an answer to each of the multiplication problems. The correct answer should be displayed after the user enters an answer. A message should be displayed informing the user that the answer entered was correct or incorrect followed by an appropriate motivating comment. A running record of the number of correct and incorrect responses must be kept. After all the problems have been presented the user must be informed of his/her performance; number of…
