OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality.
os.write() method in Python is used to write a bytestring to the given file descriptor.
A file descriptor is small integer value that corresponds to a file that has been opened by the current process. It is used to perform various lower level I/O operations like read, write, send etc.
os.write() method is intended for low-level operation and should be applied to a file descriptor as returned by
Syntax: os.write(fd, str)
fd: The file descriptor representing the target file.
str: A bytes-like object to be written in the file.
Return Type: This method returns an integer value which represents the number of bytes actually written.
Number of bytes written: 51
