Program Plan:
- Define a function “Function()” to sort and merge values in files.
- Compare values in both input files.
- Compare first two elements and write the smallest element to output file first followed by the other one.
- Continue the process until all elements are been compared in both lists.
- Compare values in both input files.
- Define a main method.
- Declare variables required for program.
- Get file names for input and output files from the user.
- Call method “Function()” to sort and merge values in files.

Write a function that takes two lists of integers X and Y as input, and computes and writes a table into a file named "question2.txt" as follows: - On each line the computations for an X,Y pair is given
Each such possible pair must exist in the file in the same order of values in X and Y
Next on each line, you provide X+Y, X*Y and X^2 + Y^2, all separated by a comma (and no spaces or other characters must exist). Note that X^2 represents "square of X".
For example, given X = [1,3] and Y=[-1,1,0], "question2.txt" should contain the following table:
question2.txt
1,-1,0,-1,2
1,1,2,1,2
1,0,1,0,1
3,-1,2,-3,10
3,1,4,3,10
3,0,3,0,9
As you can see, the first line is computed for X=1, Y=-1. The second line is built for X=1, Y=1; and the third line is for X=1, Y=0. It goes on like this, until X=3, Y=0.

using CSV write a function that takes a list of strings as inputs, and returns a single string created by joining all the input strings together, with a comma separating them.
Now write another function that takes a list of lists of strings, applies the operation from question 1 to each list, and writes the result as a row of an output file. The function should return the path to the file where the strings were written.
3. Now, write the reverse of question 2: write a function that takes in a filename (which we will assume is a CSV), and returns a list of lists of strings, where one row in the file corresponds to one list in the output list (and each value between the commas in the file row is one element in the list).
Write a function that takes two lists of integers X and Y as input, and computes and writes a table into a file named "question2.txt" as follows:
- On each line the computations for an X,Y pair is given - Each such possible pair must exist in the file in the same order of values in X and Y- Next on each line, you provide X+Y, X*Y and X^2 + Y^2, all separated by a comma (and no spaces or other characters must exist). Note that X^2 represents "square of X".
For example, given X = [1,3] and Y=[-1,1,0], "question2.txt" should contain the following table:
----- question2.txt -----1,-1,0,-1,21,1,2,1,21,0,1,0,13,-1,2,-3,103,1,4,3,103,0,3,0,9-------------------------
As you can see, the first line is computed for X=1, Y=-1. The second line is built for X=1, Y=1; and the third line is for X=1, Y=0. It goes on like this, until X=3, Y=0.

In order to change colors, you must first use the GetStdHandle function to get a handle to the console, which is similar to getting a file pointer before working with a file. It is done e.g. as follows: HANDLE hConsole; hConsole = GetStdHandle (STD_OUTPUT_HANDLE); The above functions are defined in windows.h Tip 2: Write a utility to find out the colors corresponding to all combinations from 0 to 255.

- consider a program that reads data from a text file called: "klingon-english.txt" (shown below). How would one construct such a program with the following conditions: 1. Ask the user to choose a Klingon consonant they want to practice with. Ask again if the user’s answer is not a valid Klingon consonant, until the user enters a valid consonant. 2. Find a Klingon word that starts with the chosen consonant (the text file contains only one word that starts with any given consonant, so you don’t need to use the random library) 3. Ask the user to translate the chosen word into Klingon 4. Print "Correct" if the user’s answer is correct 5. Print "Sorry, you’re wrong!" if the user’s answer is wrong 6. Print The correct answer is ... if all three user’s answers are wrong You will also factor in this version: 7.

- USE PYTHON Before there were emoji, there were emoticonsLinks to an external site., whereby text like :) was a happy face and text like :( was a sad face. Nowadays, programs tend to convert emoticons to emoji automatically! In a file called faces.py, implement a function called convert that accepts a str as input and returns that same input with any :) converted to ? (otherwise known as a slightly smiling faceLinks to an external site.) and any :( converted to ? (otherwise known as a slightly frowning faceLinks to an external site.). All other text should be returned unchanged. Then, in that same file, implement a function called main that prompts the user for input, calls convert on that input, and prints the result. You’re welcome, but not required, to prompt the user explicitly, as by passing a str of your own as an argument to input. Be sure to call main at the bottom of your file. ( Please see attached file for Demo) use PYTHONarrow_forwardAt the end of this and other textbooks, there usually is an index that lists the pages where a certain word appears. In this problem, you will create an index for a text but, instead of page number, you will use the line numbers. You will implement function index() that takes as input the name of a text file and a list of words. For every word in the list, your function will find the lines in the text file where the word occurs and print the corresponding line numbers (where the numbering starts at 1). You should open and read the file only once Create the python function as part of a python program. The data required for the function should be created in the python program and passed to the function. its an exercise pyrthon problem 6.27arrow_forwardWrite a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below. File 1 and file 2 are supplied. Here is an algorithm to merge the data from two files: Read a line from each data file While the end of both files has not been reached While the end of both files has not been reached Write the line from file 1 to the output file and read a new line from file 1. Else Write the line from file 2 to the output file and read a new line from file 2. Write the remaining lines (if any) from file 1 to the output file. Write the remaining lines (if any) from file 2 to the output file. See the Merging Filesslides attachedto the project in Canvasfor a visual look at this algorithm.arrow_forward
