- 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…iii.Now you will implement your algorithm as Python code, modifying the provided Python program Word_List_Flashcards.py. Complete the new version of show_flashcard() by modifying the code so it implements the algorithm you produced in part i. Also modify the docstring for the show_flashcard() function and the docstring for the program as a whole, to take account of the changed functionality and behaviour. Important: Do not make change to any other parts of the program.In htmlWrite program in which we access the data from delimited text file.
- 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…A python function opens file data.csv, reads the data from the file and spits the data into three columns, x, y and z. The data is then printed out.

- 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…Given Triangle struct (in files Triangle.h and Triangle.c), complete main() to read and set the base and height data members of triangle1 and of triangle2, determine which triangle's area is smaller, and output that triangle's info, making use of the relevant Triangle functions. Ex: If the input is: 3.0 4.0 4.0 5.0 where 3.0 is triangle1's base, 4.0 is triangle1's height, 4.0 is triangle2's base, and 5.0 is triangle2's height, the output is: Triangle with smaller area: Base: 3.00 Height: 4.00 Area: 6.00 412800.2778464.qx3zqy7 LAB ACTIVITY 1 #include 2 3 #include "Triangle.h" 8 9 5 int main() { 6 7 Triangle triangle1 = InitTriangle(); Triangle triangle2 = InitTriangle(); PANNENDE 10 double userBase; 9.11.1: LAB: Triangle area comparison 11 double userHeight; 12 13 14 // TODO: Read and set base and height for triangle1 (use SetBase () and SetHeight()) 15 // TODO: Read and set base and height for triangle2 (use SetBase () and SetHeight()) 16 Current file: main.c 17 0/10 Load default…Problem 1 In this problem, we want to sort an input array. Problem 1A (easier) In this problem, develop an algorithm that, given an unsorted array, creates a new array which is the sorted version of the given array. Here is the main idea of the algorithm: first scan through the original input array, finding the smallest element, and then insert this element into the beginning (index 0) of the new array, and remove this smallest element from the input array. Next, scan the (shortened) input array again, finding the smallest element, and then insert it into the next available position of the new array and remove it from the input array. Repeat the process until the original array becomes size 0 (also the new array contains all the values in the original input array). Develop flowchart for this algorithm, Hint: you will need nested loops for doing the work in one main algorithm. You can also write a sub- program to do some work. In this case the main algorithm has one loop. Hint: to find…

(e.g. John is 18 years old and is studying Computer Science.) Within the template literal, use object dot notation to access the name, age, and major properties of the student object. Use a console.log() to print out the formatted string for each student.
