Python | os.sysconf_names 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.

os.sysconf_names object in Python is a dictionary mapping of names accepted as parameter by os.sysconf() method to the integer values defined for those names by the host operating system. This object is used to determine the set of names known to the system.

Note: os.sysconf_names object is available only on UNIX platforms.



Syntax: os.sysconf_names

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

Return Type: This object returns a dictionary having set of names known to the operating system as key and their corresponding integer value (defined by operating system) as value.
