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!

Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Question

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

POSITIVE REVIEW WILL BE LEFT FOR CORRECT LANGUAGE ONLY AND NOT COPY PASTE FROM INCORRECT ANSWER A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg…
Complete the following incomplete program (begin by copy-pasting that into a new program file). The completed program will provide a user interface to draw as many circles as the user wants only by clicking in the window. After getting the number of circles (n) to draw as input from the user through the provided interface, the program should iterate n times. In each iteration it should wait for the user to click twice and draw a circle with center at the point where the user clicked first and with radius calculated as its distance from the second point where the user clicked. It should then fill the circle with a random color. Hints: Distance between two points with coordinates x1 & y1 and x2 & y2 and can be calculated as sqrt((x1-x2)2 + (y1-y2)2 ). To generate a random color, use randint(0,255) from the random libray to generate a random number between 0 and 255 (both inclusive). Use it three times to get the r, g and b values to generate a random color from graphics import…

This Python Lab 9 Lab: Write a file copying program. The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file). The program opens the source file for reading and the destination file for writing. As the program reads each line from the source file and it writes the line to the destination file. When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful. Source file: add.py print("This program adds two numbers") a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print(f"{a} + {b} = {a+b}") Destination file:…

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,…
