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.
All functions in os module raise OSError in the case of invalid or inaccessible file names and paths, or other arguments that have the correct type, but are not accepted by the operating system.
os.fchown() method in Python is used to change the owner and group id of the file associated with the specified file descriptor to the specified numeric owner id (UID) and group id (GID). This method is equivalent to
os.chown(fd, uid, gid) method.
os.fchown() method is available only on UNIX platforms and the functionality of this method is typically available only to the superuser or a privileged user.
Syntax: os.fchown(fd, uid, gid)
fd: A file descriptor representing the file whose uid and gid is to be set
uid: An integer value representing the owner id to be set for the file.
gid: An integer value representing the group id to be set for the file. To leave any one of the ids unchanged, set it to -1.
Return Type: This method does not return any value.
