Exercise 1: Write a Python program that reads from the user the name of two files (an input file and an output file). The program will then read each line of the input file and save it in the output file preceded with the line number and removing any of the following punctuations (. , !?; :) found at the end of the line. For example, if the input file is: Mary had a little lamb; Whose fleece was white as snow; And everywhere that Mary went; The lamb was sure to go! Then the output file the content of the input file and saves it in the produced output file will be Line 1: Mary had a little lamb Line 2: Whose fleece was white as snow Line 3: And everywhere that Mary Line 4: The lamb was sure to go

Python programming language    Write a program that asks the user for a number. Write the number to a file called total.txt. Then ask the user for a second number. Write the new number on line 2 with the total for both numbers next to it separated by a comma. Then ask the user for a third number and do the same. Keep asking for numbers until the person puts in a zero to terminate the program. Close the file. Be sure to use at least 2 functions [main() and total_numbers(number, total)]. Put all inputs and outputs into the main function, with all calculations into the total_numbers function.   Give me a number: 13 Give me another number: 14 14 + 13 = 27 Give me another number: 3 3 + 27 = 30 Give me another number: 4 4 + 30 = 34 Give me another number (0 for quit): 0 Your total is 34.       Write a program that displays the lines from the total.txt file in the following output. Use a try catch phrase to check for errors. Use only one function for this portion [main()].   13 14, 27 3,…

The next three questions concern a program that opens a scores file provided by the user, reads it one line at a time, adds the scores as floating point numbers to a list scores, and then computes the average score. The example file scores.csv looks like this: Student Name, Test Score Jinyue, 98.5 Adesh, 97.4 Pinn, 99.1 Arindaam, 97.2 The first part of the program opens the file and reads just the first line into the variable header. # Open the Filename and ignore the first line filename= input("Enter filename:") open (filename) fhand = header = Fill in the blank to complete the program fragment:

The objective of this problem is to show that you can write a program that reads a text file and uses string methods to manipulate the text. File cart.txt contains shopping cart type data from golfsmith.com representing the gifts you have purchased for your dad for this past Fathers Day. Good for you. You have been very generous! The first item in each row of the file is the part number, the second the quantity, the third the price and the fourth the description. Your program will read the file line by line and compute the total cost of all of the items in the list. You will then display a message that looks like this, assuming the cost of each item adds up to 168.42: Here's what your output should look like: The total price for the awesome Fathers Day gifts you bought is $168.42. The shopping cart can be found here: cart.txt. Right click on the link and save the file to the folder where you have your Python files.
