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)When an input file is opened, its read position is initially set to the first item in the file. True or False

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…

- A file named data.txt contains an unknown number of lines, each consisting of a single integer. Write a program that creates the following three files: dataplus.txt dataminus.txt zeros.txt The program should read each line of the data.txt file and perform the following: If the line contains a positive number, that number should be written to the dataplus.txt file. If the line contains a negative number, that number should be written to the dataminus.txt file. If the line contains the value 0, do not write the value to a file. Instead, keep a count of the number of times 0 is read from the data.txt file. After all the lines have been read from the data.txt file, the program should write the count of zeros to the zeros.txt file.Chapter 4.
