- In Python, Create a program that will write 100 integers created randomly in a file. The integers will be separated by a space in the file. Read the data back from the file, and display the sorted data. The program should prompt the user to enter a file name. Utilize the following function headers for this problem: Main() WriteNumbers(filename) ReadNumbers(filename) The main function will first prompt the user to enter the filename. Then the main function calls WriteNumbers-then ReadNumbers. The WriteNumbers function opens an output file and writes 100 random numbers as long a large string text. Do not use lists for this problem- please just write a random number followed by a space 100 times. The ReadNumbers function will then read the text file and display the numbers sorted. In order to sort the numbers, read the big string and then split it into a list. Now convert them into integers by using list comprehension and then sort the list. Loop through the list and print each…arrow_forwardIn Python, Write a program that prompts the user for a file name. (Use problem 2.txt file) Each line of the file should be preceded by a line number followed by a colon in the program. The numbering of lines should begin at number 1. BE SURE THERE ARE NO EXTRA SPACE BETWEEN THE LINES. problem 2.txt file contents: Python language is incredibly easy to use and learn for new beginners and newcomers. The python language is one of the most accessible programming languages available because it has simplified syntax and not complicated, which gives more emphasis on natural language. Due to its ease of learning and usage, python codes can be easily written and executed much faster than other programming languages. Sample output: Answer Enter a file name: Problem 2.txt line 1 Python language is incredibly easy to use and learn line 2 for new beginners and newcomers. The python language line 3 is one of the most accessible programming languages line 4 available because it has…arrow_forwardPYTHON PROGRAMMING ONLY PLEASE (PLEASE INCLUDE INPUT VALIDATIONS IF NECESSARY) Write a program that writes a series of random numbers to a file. Each random numbershould be in the range of 1 through 500. The application should let the user specify howmany random numbers the file will holdarrow_forward

Your program should read the name of the student, the four grades, and the year of birth from the file, then calculate the average, and then print the student name, grades, and average on the computer screen. The program should also find the age of the student and whether his/her year of birth is a leap year or not and print that on the screen. »arrow_forward
