Python method write() writes the string str to file descriptor fd. Return the number of bytes actually written.
Following is the syntax for write() method :
os.write(top[, topdown=True[, onerror=None[, followlinks=False]]])
This method returns the number of bytes actually written.
Python following example shows the usage of write() method.
# !/usr/bin/python import os, sys # Open file fd = os.open("f1.txt",os.O_RDWR'os.CREAT) # Writing text ret = os.write(fd,"This is test") # ret consists of number of bytes written to f1.txt print "the number of bytes written: " print ret print "written successfully" # Close opened file os.close(fd) print "Closed the file successfully!!"
When we run the above program, it produces the following result:
the number of bytes written: 12 written successfully Closed the file successfully!!
