- How do i replace a string from a file with a new stringHow can I efficiently change a string's location in a file?JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. 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 may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…
- What is the most effective method for updating a string that is already present in a file?Using PHP Write a program using PHP programming language that reads the user name and password from a login form Login.html Login.php And then writes them in a text file(logos.txt).What happens if you enter a string greater than eight characters? How can a buffer overflow be avoided?
- Python The filescores.txt contains a list of names and test scores. Create a program named that reads each line of the file and determines the highest score and who obtained it. Since the lab is an exercise in strings, you must use at least one string method to determine the names and the scores.The python function first_words takes one parameter, fname, the name of a text file, and returns a list containing the first word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["apples", "bananas", "limes"] should be returned.NOTE: You may assume the file will contain no blank lines.BIG HINT: If line is a string representing a line of text (inside of a for loop!), then L = line.split() creates a list of the words in the line.【Python Programming】Writing a game is _word_drome(), a Chinese string palindrome that determines whether the content is given, all non-English words are loaded, and the Chinese string is required to be read from the file.
- Computer Science Python! Compose a program that reads in a csv file filters and splits the data. For example given example.csv PYTHON please! lebron james 55 michael jordan 35 allen iverson 89 ouput creates 2 new files one with lebron michael allen and the second one with leaving the numbers out due to the filter james jordan iversonProgram that reads a string from the user and append it into a file.PYTHON!!!! Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number. An example file and the program input and output is shown below: example.txt Line 1. Line 2. Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines. Enter a line number [0 to quit]: 0 The program works as expected for given input, test 1: Custom Test: Delete file at start Test Contents: import os.path try: os.remove('.test.txt')…
