File names: color_square.py, chessboard.py, test_squares.py Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…
Muscat marketing research company is conducting a rating survey of different chains of supermarkets. The rating is over 5 stars (*****), a Text file is provided with two columns, one holds the name of supermarkets and the other column holds rating in stars. Find the list below of 9 supermarkets about whom rating is being conducted. Each star is equal to 1 point. Suppose a supermarket get ** means it has got points. A market is rated more than once, so the formulae is sum of points of each market /number of times rated. Note: Program solution must use functions and arrays only. Download rating.txt from moodle. Rating.txt is containing 100 records, so you may declare array size as 100 as a global variable.

In Python Prompt the user for a text file that contains a list of student names, one on each line. Also prompt the user for a CSV file that contains scores for the students in the following order: homework1, homework2, midterm exam, final exam. Each line in the CSV has four scores, delimited by a comma. Each name in the text file has the corresponding scores in the CSV file. You will need to calculate the weighted final grade for each student as follows: 5% homework1 5% homework2 40% midterm exam 50% final exam Homework is scored out of 10 points and exams are scored out of 100 points. You need to create a program that will read the scores from the CSV file, calculate the weighted final grade, and display the resulting final grade, along with the student's name. Sample input files are attached. You can assume that the same number of lines will be in the input files, and that the order of the names and corresponding grades is the same in the two files. Display the name and final grade…
Edit the isPrime function so that it returns False when any number less than 3 is passed (including negative numbers). Then write a function called nPrimes that accepts an integer parameter called n and then prints the first n prime numbers. Start looking for prime numbers at 3, and keep looking until you find n of them. Your nPrimes function should use the isPrime function to determine if a number is prime. Both of these functions should be placed in a file called NPrimes.py. Here is a sample run of the completed program: Enter the number of primes you want to find: 10 3 5 7 11 13 17 19 23 29 31 from NPrimes import nPrimesdef main(): n = int(input("Enter the number of primes you want to find: \n")) nPrimes(n) main() def isPrime(num): prime = True for x in range(2, num): if num % x == 0: prime = False break return prime;
Do not read directly from the example files, as the automated testing system expects you to read from the standard input. Instead, process the lines as follows: 3 - Geography Grades 3 Make a copy of your program for the problem Geography Grades 2 and change the code in such a way that your program can process multiple groups. These groups are on the input separated by ’=\n’. Every group starts with a first line that contains the name of the group and the lines after contain the information about the students in the same way as is specified for the problem Geography Grades 1.

Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file, each on its own line.*Note that the contents of the file AcctNumsIn.txt will change when the test is run to test the program against different input.

Python exercice. consider the atttached file for further details. Old-fashioned photographs from the nineteenth century are not quite black and white and not quite color, but seem to have shades of gray, brown, and blue. This effect is known as sepia, as shown in the figures below. Original Sepia Original Image & Sepia Image Write and test a function named sepia that converts a color image to sepia. This function should first call grayscale to convert the color image to grayscale. A code segment for transforming the grayscale values to achieve a sepia effect follows.Note that the value for green does not change. (red, green, blue) = image.getPixel(x, y)if red < 63: red = int(red * 1.1) blue = int(blue * 0.9)elif red < 192: red = int(red * 1.15) blue = int(blue * 0.85)else: red = min(int(red * 1.08), 255) blue = int(blue * 0.93) images.py To instantiate an image from a file, enter image = Image(aGifFileName) To…

Each line contains the name of a person (possibly containing multiple words) followed by the year of his birth. Abbas ibn Firnas ibn Wirda: 809 Muhammad ibn Musa al-Khwarizmi: 780 Abu Al-Walid Muhammad Ibn Alımad Ibn Rushd: 1126 The program uses function extractDataRecord with the specification: @param infile the input text file object @return parts a list containing the name (string) in the first element and the year of birth (int) in the second element. If the end of file was reached, an empty list is returned Drag and drop statements from the following selection: main() f= open("input.txt", "r") def main(): record = f.readline() print(record[0]+"was born in "+str(record[1) def extractDataRecord(infile) : parts = line.split(":", 1) return (] line = infile.readline() parts[1] = int(parts[1]) if line == "": else: return parts parts = line.split(") parts =…
In a text file, I have two numbers each line. The numbers are the employee ID and the number of hours the employee work. My goal of this program is to read the both employee ID and the number of hours the employee work and print it out in the main program. If the list of employee id is not in order, sort it in order and still print it out in the main program. Additionally, after printing them out, print out the total number of employees and the total number of hours all the employee work. Write this in java For example File.txt EmployeeID Number of Hours Work 3 12 2 20 1 40 5 20 7 9 In the main program print: EmployeeID Number of Hours Work 1 40 2 20 3 12 5 20 7 9
In Python Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Ex: If the input of the program is: movies.csv and the contents…
