Answer the given question with a proper explanation and step-by-step solution.
1- Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, then closes the file.
File Iteration: Introduction
A text file is essentially a sequence of lines. Here is a typical coding pattern for processing each line of a file in turn:
Open the file for reading.
Use a for loop to iterate over the lines of text, executing a block of one or more statements to process each line.
Close the file.
Finish processing (print, return, etc.) if needed
NOTE: You will need to use this pattern, or some variation of it, to solve the remaining coding problems in this assignment.
As the following for loop iterates through each line of the file, the loop variable (`line`) represents the current line of the file as a string of characters.
myFile = open("someTextFile.txt", "r") for line in myFile: do something on each iteration do a second thing on each iteration etc... myFile.close()
PROBLEM: Read a string from standard input using python. Then, iterate over a text file called "cards.txt" and, for each line of the file that starts with the string read from standard input,…

- Please I really need help with this question it is confusing me a lot I don't understand how should I start, Also can you please attach the TEXT FILE Screenshot. PLEASE! Write a program that allows the user to navigate lines of text in a file. The program should prompt the user for a filename, read the file 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 number range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the text associated with that number. You must also run the script and provide a screenshot of the output along with the textfile.arrow_forwardThe Spring fork amateur golf club has a tournament every weekend. The club president has asked you to design a program. It contains the following menu: Select the task 1. Add new records 2. Read Records 3. End the program If the user enters 1, the program will read each players name and golf score as keyboard input, then save the records in a file names golf.dat If the user enters 2, the program reads the records from the golf.dat file and displays them. While the menu selection is not equal to 3, get the user selection. If the selection is 1, get the number of players in the tournament, open the output file. For each player, get the name and the score, and write them to the file. Close the file. If the selection is 2, open the input file, read the values from the file, display the values, close the file. If the selection is 3, exit the program. I already had a code written from before, but I'm having a hard time turning it into a menu driven code.

- 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.
