- You develop a Python application for your school.You need to read and write data to a text file. If the file does not exist, it must be created. If the file has content, the content must be removed.Which code should you use? Group of answer choices C. open(“local_data”, “w+”) D. open(“local_data”, “w”) A. open(“local_data”, “r”) B. open(“local_data”, “r+”You develop a Python application for your school.

Group of answer choices open(“local_data”, “r”) open(“local_data”, “w+”) open(“local_data”, “r+”) D. open(“local_data”, “w”)The File class contains file input and output operations. In other words, you can use the File class to read and write content from and to files. True False
- In Python Write a program that reads the contents of a text file and inserts the line numbers at the beginning of each line, then rewrites the file contentsThe python function get_second_line takes one parameter, fname, the name of a text file. The function should open the file for reading, determine the second line of the file, close the file, and return the second line (a string). NOTE: You may assume the file will have at least two lines.2. File handling is an important part of any application. Assume that, you are asked to build an application to find the harmonic mean in a file. Assume that you have to read the file of "Filel.txt" and print the harmonic mean of each row to an output file "File2.txt". All of the data in the "File1.txt" is comma separated. In file1.txt you are given the name of the data set in first place, then you are given the data list. All of them are comma separated. Your task is to compute the harmonic mean from the given file | for each dataset. The file may contain more than 1000 rows. Write your code by following the requirements. File2.txt harmonic mean of Datal is 3.50 harmonic mean of Data2 is 3.43 harmonic mean of Data3 is 3.50 File1.txt Data1, 3, 4, 4, 3, 3.7, 4, 3.3, 1 Data2, 3, 4, 3.7, 3, 3.7, 4, 3, 1 Data3, 3, 4, 4, 3, 3.7, 4, 3, 2 Data4, 3, 4, 4, 3, 3.7, 4, 3.3, 2 Design a JAVA application that can perform the task with the given scenario. harmonic mean of Data4 is 3.49
- 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.

- The Springfork Amateur Golf Club has a tournament every weekend. The club president has asked you to design two programs. (1) A program that will ask the user how many golfers will be entered, read each player's name and golf score as keyboard input, and then save these records in a file named golf.txt. (Each record will have a field for the player's name and field for the player's score.) (2) A program that reads the records from the golf.txt file and displays them. Please submit three things: 1.) Flowchart for both programs (can be in one document or in two separate documents) 2.) Pseudocode for both programs (this can be on the same document as your flowcharts) 3.) Python source code files - one for each program (.py file) PYTHON pleaseWrite a program that asks the user for the name of a file. The program should display onlythe first five lines of the file’s contents. If the file contains less than five lines, it shoulddisplay the file’s entire contents.
