Python | os.sysconf_names object

| | |

The os.sysconf_names object in Python is a dictionary that maps names taken as a parameter by the method os.sysconf () to the integer values ​​defined for these names by the host operating system. This object is used to define a set of names known to the system.

Note: os.sysconf_names is only available 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.

Code: using the os.sysconf_names object

# Python program to explain the os.sysconf_names object

 
#import the os module

import os

 
# import pprint module

import pprint

 
# Get the dictionary display
# names accepted by os.sysconf ()
# their corresponding integer values ​​
# defined by host OS

names = os.sysconf_names

  

  
# print the dictionary display
# use pprint

print ( " The list of names known to the operating system: " )

pprint.pprint (names, width = 1 , height = 1 )

Exit :
