Python | os.supports_fd object

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.

Some method in OS module permit specifying their path parameter as an open file descriptor (fd). As different platforms provide different functionality, fd parameter might be supported on one platform but not supported on another. os.supports_fd method in Python is a set object which indicates which methods in the OS module permit specifying their path parameter as an open file descriptor.

Whether a particular method permits specifying its path parameter as an open file descriptor or not, can be checked using in operator on os.supports_fd .
For example:
Below expression checks whether os.stat() method permits specifying their path parameter as an open file descriptor or not when called on your local platform.

os.stat in os.supports_fd

Syntax: os.supports_fd

Parameter: This is a non callable set object. Hence, no parameter is required.

Return Type: This method returns a set object which represents the methods in the OS module, which permits specifying their path parameter as an open file descriptor.
