dir_fd (optional) : A file descriptor referring to a directory.
The default value of this parameter is None.
If the specified path is absolute then dir_fd is ignored.
Note: The ‘*’ in parameter list indicates that all following parameters (Here in our case ‘dir_fd’)
are keyword-only parameters and they can be provided using their name, not as positional parameter.
Return Type: This method does not return any value.
