all
occurences
of
words, characters and lines

3) create
random
integers

import os.path
import random

fileToWrite.flush()
fileToWrite.close()

with open(filename, "r") as fileToRead:
    for line in fileToRead:
# print(line.split(" "))
randNumber = [int(x) for x in line.split(" ") if len(x) > 0]
# print(randNumber)

with open(filename, 'w+') as fileToWrite:
    for elem in sorted(randNumber, key=int):
        sortedNumber = sortedNumber + " " + str(elem)
fileToWrite.write(sortedNumber)
fileToWrite.flush()
fileToWrite.close()


def main():
    filename = input("Enter file name: ")


if os.path.exists(filename):
    print("The file already exist")
else:
    writeRandomNumbers(filename)

main()
