Python| os.confstr_names 对象

Python中的OS 模块提供了与操作系统交互的功能。操作系统属于 Python 的标准实用程序模块。该模块提供了一种使用操作系统相关功能的可移植方式。
Python中的os.confstr_names对象是os.confstr()方法作为参数接受的名称到主机操作系统为这些名称定义的整数值的字典映射。此对象用于确定系统已知的名称集。
注意： os.confstr_names对象仅在 UNIX 平台上可用。

Syntax: os.confstr_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. 
 

代码：使用 os.confstr_names 对象

Python3

# Python program to explain os.confstr_names
   
# importing os module
import os
 
# importing pprint module
import pprint
 
# Get the dictionary mapping of
# names accepted by os.confstr() method
# to their corresponding integer values
# defined by host OS
names = os.confstr_names
 
 
# print the dictionary mapping
# using pprint
print("The list of names known to the operating system:")
pprint.pprint(names, width = 1)

输出：

The list of names known to the operating system:
