Code should be in Python.
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.
(Examples in image)
Write code that opens an output file with the filename number_list.txt, but does not erase the file’s contents if it already exists.
Write a write_scores function that opens the file, and writes scores and names from lst_scores and lst_names into the file. An example function call is below. Make sure to handle a file error. Assume good input in both lists.
Function name: write_scoresParameters: lst_scores, a list of ints; lst_names, a list of strings; file_name, a string Purpose: Writes the names and scores to the file name, with one name and one corresponding score per line.Example function call:

After this code runs, the file final_grades.txt should read:

- 12.7: Sentence Filter C++Write a program that asks the user for two file names. The first file will be opened for input and the second file will be opened for output. (It will be assumed that the first file contains sentences that end with a period.) The program will read the contents of the first file and change all the letters to lowercase except the first letter of each sentence, which should be made uppercase. The revised contents should be stored in the second file. Prompts And Output Labels. Input Specification.

Word Separator (modified *** Read carefully ***) Write a program that prompts the user to enter a file name, then opens the file in text mode and reads it line by line. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file can contain one or more sentences. The program should accept as input each sentence in which all the words are run together, but the first character of each word is uppercase. Convert sentences to strings in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string StopAndSmellTheRoses.” would be converted to “Stop and smell the roses.” Sentences are separated by periods ('.'), exclamation marks ('!'), or…arrow_forward7.8 LAB: Word frequencies (lists) Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method.
