Python time.monotonic()用法及代碼示例

Python中的時間模塊提供了各種與時間相關的函數。

time.monotonic()Python中的時間模塊方法用於獲取單調時鍾的值。單調時鍾是不能向後移動的時鍾。由於未定義單調時鍾返回值的參考點，因此僅連續調用的結果之間的差有效。

用法： time.monotonic()

參數：不需要任何參數。

返回類型：此方法返回一個浮點值，該值表示小數秒內的單調時鍾的值。

代碼1：用於time.monotonic()獲得單調時鍾值的方法

# Python program to explain time.monotonic() method 
  
# importing time module 
import time 
  
# Get the value of 
# a monotonic clock using 
# time.monotonic() method 
value = time.monotonic() 
  
# print the value of  
# the monotonic clock 
print("Value of the monotonic clock (in fractional seconds):", value)

輸出：

Value of the monotonic clock (in fractional seconds): 2116.429736057

代碼2：用於time.monotonic()在長時間運行過程中測量經過時間的方法。

# Python program to explain time.monotonic() method 
  
# importing time module 
import time 
  
# Get the value of 
# a monotonic clock at the  
# beginning of the process 
# using time.monotonic() method 
start = time.monotonic() 
  
# print the value of  
# the monotonic clock 
print("At the beginning of the process") 
print("Value of the monotonic clock (in fractional seconds):", start) 
  
i = 0
arr = [0] * 10; 
while i < 10: 
    # Take input from the user 
    arr[i] = int(input()) 
    i = i + 1
  
# Print the user input 
print(arr) 
  
# Get the value of 
# monotonic clock  
# using time.monotonic() method 
end = time.monotonic() 
  
# print the value of  
# the monotonic clock 
print("\nAt the end of the process") 
print("Value of the monotonic clock (in fractional seconds):", end) 
print("Time elapsed during the process:", end - start)

輸出：

At the beginning of the process 
Value of the monotonic clock (in fractional seconds): 3957.237067598

10
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

At the end of the process
Value of the monotonic clock (in fractional seconds): 3966.407866892
Time elapsed during the process (in fractional seconds): 9.170799294000062
