# !/usr/bin/python3
import os, sys

# Open a file
fd = os.open( "f1.txt", os.O_RDWR|os.O_CREAT )

# Write one string
line = "this is test"

# string needs to be converted byte object
b = str.encode(line)
ret = os.write(fd, b)

# ret consists of number of bytes written to f1.txt
print ("the number of bytes written: ", ret)

# Close opened file
os.close( fd)

print ("Closed the file successfully!!")
