Python | os.device_encoding() method - ❤️️ Online Python tutorial

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.

Code: Use of os.device_encoding() method to get the encoding of the device associated with the given file descriptor

# Python program to explain os.device_encoding() method   
  
# importing os module  
import os 
  
# File path 
path = "/home/ihritik/Desktop/file.txt"
  
# Open the file and get  
# the file descriptor associated 
# with it using os.open() method  
fd = os.open(path, os.O_RDWR | os.O_CREAT) 
  
  
# Check if file descriptor fd 
# is open and connected 
# to a terminal using os.isatty() method 
print("Connected to a terminal:", os.isatty(fd)) 
  
  
# Print the encoding of 
# the device associated with 
# the file descriptor fd 
# using os.device_encoding() method 
print("Device encoding:", os.device_encoding(fd))  
  
  
# Open a new pseudo-terminal pair 
# using os.openpty() method 
# It will return master and slave  
# file descriptor for  
# pty ( pseudo terminal device) and 
# tty ( native terminal device) respectively 
master, slave = os.openpty() 
  
# Check if file descriptor master 
# is open and connected 
# to a terminal using os.isatty() method 
print("Connected to a terminal:", os.isatty(master)) 
  
  
# Print the encoding of 
# the device associated with 
# the file descriptor master 
# using os.device_encoding() method 
print("Device encoding:", os.device_encoding(master))  

Output:

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