In python, 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. 1.

• • Asks the user for their name and store it in an array Asks the user for their age and store it in a variable Determines how many years before they can retire at age 67. If user is 67 then it will indicate that the user should retire now. If user is over 67 it will indicate that the user should have already retired If the user is under 67 then it will indicate number of years before retirement Ends with a thank you message. Example of Output Welcome to nameage Please enter name: (user enters a value like Pat) Please enter your age: (user enters a value like 69) Hi Pat. You should already be retired. Thank you for using nameage. Bye!
In Python: The Broadway dataset contains data for Broadway shows' Capacity (percentage of the theatre filled) and Gross Potential (maximum amount that can be earned) for multiple shows in a specific month and year. Given a CSV file name read from user input, write a program that performs the following tasks: Read in the CSV file as a dataframe. Insert a new column labelled "Size" at the end of the dataframe. The "Size" column contains values in column "Gross Potential" divided by 2. Output the dataframe using the print() function. Create a scatter plot of "Gross Potential" vs "Capacity" with the following marker styling parameters: markers: 'x' color: orange size: values in column "Size" Add the x-label ("Capacity", fontsize = 10), y-label ("Gross Potential", fontsize = 10), and title ("Gross Potential vs Capacity", fontsize = 16) to the figure. Add gridlines to the figure using '--' as linestyle. Save the figure as output_fig.png. Click here to view Input and Output Example
The grayscale2 function is already written, you just need to write inside it how to convert an image to grayscale using the crude average of RGB: from images import Image def grayscale1(image): """Converts an image to grayscale using the psychologically accurate transformations.""" for y inrange(image.getHeight()): for x inrange(image.getWidth()): (r, g, b) = image.getPixel(x, y) r = int(r * 0.299) g = int(g * 0.587) b = int(b * 0.114) lum = r + g + b image.setPixel(x, y, (lum, lum, lum)) def grayscale2(image): """Converts an image to grayscale using the crude average of the r, g, and b""" pass def main(): filename = input("Enter the image file name: ") image = Image(filename) grayscale2(image) image.draw() if __name__ == "__main__": main()

Declare a variable named num with an initial value of 0. Create a while loop that will print "Keep going" as long as the value of num is less than 5. Use window.alert() for displaying the output. Create a function named showProd that returns the product of n1 and n2. Using the new keyword, create an array named info with three (3) values: your first name, your nickname, and your last name.
Part II: Image Representation An image is an array, or a matrix, of pixels (picture elements) arranged in columns and rows. RGB is one of the models used in color pixels. In a color image, each RGB pixel is an integer number which contains the mixture of red, green and blue colors. In this assignment, you will be provided with an image data file, image.dat. The first line in data file contains the height (rows) and width (columns) of the image. The following lines gives the red, green and blue color integer values for each pixel. The following sample.dat is given as an example: (The given example can be seen on the picture down) According to this input file, the image has 4 rows and 2 columns. The pixel at [0][0] has red value 117, green value 117 and blue value 245. Write a Java program that reads from the given input file and creates an RGB image object with the given width and height. Then, it'll read red, green and blue color values for each pixel from data file, and calculate RGB…
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. Hints: Use the find() function to find the index of a comma in each row of…
Please submit a flowchart of your program for your project below. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final average or grade. I would like the system to display the…

"In the student sample program files for this chapter, you will find a text file named house_prices.csv. The file contains the following data about houses for sale in a city: Price Number of bedrooms Number of bathrooms Square feet of living space The data stored in each line is formatted in the following way: Price,Bedrooms,Bathrooms,SquareFeet Notice that the data items are separated by commas. The first line in the file looks like this: 221900,3,1,1180 The data stored in this line is: Price = $221,900 Bedrooms = 3 Bathrooms = 1 Square feet = 1,180 Design a class that has properties for the four pieces of data. In an application, read the file and store each house’s data in an instance of the class. The class instances should be stored in a List. The application should let the user search the List for the prices of houses with the number of bedrooms within a range, the number of bathrooms within a range, and the square feet of living space within a range.
