- Line Numbers Write a program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. PythonQuestion 55 Write a function that takes two parameters, a file name to create and an integer. The function should write all the even numbers between 0 and the integer to the file name passed in. The numbers should be all on one line of the file For example: write_evens("even_file.txt",20) This should create a file called even_file.txt that contains 0 2 4 6 8 10 12 14 16 18 20 Full explain this question and text typing work only thankspython function that creates and saves data in a file. the saved data represents exam grades. in the function , you will create n random numbers in the range 1-100, where n is the number of students. The function can be called as follows: createFile(filename, n) main function, in which the user inputs the file name and the number of students, then the main calls function createfile. the main should preform validation for n (should be > 0), and the filename(should end with .txt)
