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.isatty() method in Python is used to check whether the specified file descriptor is open and connected to a tty(-like) device or not. “tty” originally meant “teletype” and tty(-like) device is any device that acts like a teletype, i.e a terminal.
A file descriptor is small integer value that corresponds to a file or other input/output resource, such as a pipe or network socket. It is an abstract indicator of a resource and act as handle to perform various lower level I/O operations like read, write, send etc.
fd: A file descriptor, whose is to be checked.
Return Type: This method returns a Boolean value of class bool. Returns True if the specified file descriptor is open and connected to a tty(-like) device otherwise, returns False.
Connected to a terminal: False Connected to a terminal: True
