Python| time.get_clock_info() 方法

Python中的时间模块提供了各种与时间相关的功能。

Time 模块中的time.get_clock_info()方法用于获取指定时钟名称的信息。此方法将信息作为命名空间对象返回。
支持的时钟名称和读取该时钟值的方法如下：

时钟： time.clock()
单调： time.monotonic()
perf_counter : time.perf_counter()
process_time : time.process_time()
线程时间： time.thread_time()
时间：时间。时间time.time()

Syntax: time.get_clock_info(name)

Parameter:
name: A string value representing the clock name.

Return type: This method returns a namespace object whose attributes represents the information about specified clock name.
Following are the attributes of namespace object:

adjustable: This is ‘True’ if the clock can be changed automatically or manually by the system administrator. Otherwise ‘False’.
implementation: The name of the underlying C function used to get the clock value.
monotonic: It’s value is true, if the clock can not go backward. Otherwise False.
resolution: This attribute specify the resolution of clock in seconds.

代码： time.get_clock_info()方法的使用

# Python program to explain time.get_clock_info() method
  
# importing time module
import time
  
# Clock name
clock_name = 'clock'
  
# Get the information on
# the specified clock name
clock_info = time.get_clock_info(clock_name)
  
# Print the information
print("Information on '% s':" % clock_name)
print(clock_info) 
  
clock_name = 'perf_counter'
  
# Get the information on
# the specified clock name
clock_info = time.get_clock_info(clock_name)
  
# Print the information
print("\nInformation on '% s':" % clock_name)
print(clock_info) 
  
clock_name = 'process_time'
  
# Get the information on
# the specified clock name
clock_info = time.get_clock_info(clock_name)
  
# Print the information
print("\nInformation on '% s':" % clock_name)
print(clock_info)

输出：

Information on 'clock':
namespace(adjustable=False, implementation='clock()',
monotonic=True, resolution=1e-06)

Information on 'perf_counter':
namespace(adjustable=False, implementation='clock_gettime(CLOCK_MONOTONIC)',
monotonic=True, resolution=1e-09)

Information on 'process_time':
namespace(adjustable=False, implementation='clock_gettime(CLOCK_PROCESS_CPUTIME_ID)',
monotonic=True, resolution=1e-09)
