Change the number 10 to 50 (using a temp.txt file)
Hint: if you want to use !
Use module os that is part of Python to manipulate files.: import os. You can use functions that come with “os” module. Functions remove and rename can be used as explained below.
rename(old_name,new_name):This function renames the old_name to new_name).
remove(filename)method in Python is used to remove or delete a file.

- 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_forwardIn C programming.

- Question 4: Quote Filename: quote.py Write a program that reads in an integer representing the number of sentences in the quote. For each sentence in the quote, the program should prompt for the length of the sentence and then read in that number of words from the keyboard. At the end of each sentence add a period ("") and go to the next line. After all of the words in the quote are read, then print the quote to the screen. For example: Number of sentences: 4 Enter length: 3 Roses are red. > Violets are blue. > There is no try. > Just do not or do.arrow_forwardPython programming help I need help of question 1 to read a file from persons.txt Write a program that takes a person’s details (name, age and a city), and writes to a file (persons.txt) using a loop repeatedly.
