Sorting Text within a .txt file

[drogers10940]

So I came up with this following code, please bear with me if it is terrible. But its not giving me any syntax errors and seems to be running. When I re-open the text file to view the newly sorted results, the text file is empty. Is this because I am "w" and not "a"?

import itertools
def main():
    inputFile= open("students.txt", 'r')
    lineList = inputFile.readlines()
    with open("students.txt", "r") as text_file:
        for line in itertools.islice(text_file,0,2):
            my_tuple = (line)
            for n in my_tuple:
                sorted(my_tuple)
                inputFile.close()
                with open("students.txt", "w") as text_file:
                    text_file.write(my_tuple)
                    close.inputFile()
main()
