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.device_encoding() method in Python is used to get the encoding of the device associated with the specified file descriptor, if it is connected to a terminal. This method returns None, if the specified file descriptor is not connected to a terminal.
Note: This method is available only on some flavour of UNIX.
Syntax: os.device_encoding(fd)
Parameter:
fd: A file descriptor, whose device encoding is to be queried.Return Type: This method returns a string value which represents the encoding of the device associated with the specified file descriptor if it is connected to a terminal, otherwise None.

Connected to a terminal: False Device encoding: None Connected to a terminal: True Device encoding: UTF-8
