python - Pythonでタイマーを作成する方法

Question

プログラムの実行時間を計ってから時間を表示する必要があるコードを作成しています。これは基本的にバックグラウンドで実行されるタイマーであり、コードが実行されている時間を表示するために呼び出すことができます。どうすればいいですか？

Answer 1

開始時刻を記録し、後でその開始時刻と現在時刻の差を計算します。

プラットフォームの違いにより、精度のためにtimeit.default_timercallableを使用する必要があります。

from timeit import default_timer

start = default_timer()

# do stuff

duration = default_timer() - start

これにより、浮動小数点値として秒単位のウォールクロック時間が得られます。

デモ：

>>> from timeit import default_timer
>>> start = default_timer()
>>> # Martijn reads another post somewhere
... 
>>> print default_timer() - start

Answer 2

これはPythonで簡単です

import time
start_time=time.time()
#do something
end_time=time.time()-start_time

結果end_timeは秒単位になります

私はこれをしました、これはあなたを助けるかもしれません

from timeit import default_timer

timerPool = {}
TIMER_RUNNING = 1
TIMER_STOPPED = 0
TIMER_IDLE = 2


"""

"""
"""
required initialization for "eightSecTimer_Id" timer
"""
timerPool['eightSecTimer_Id'] = {}
timerPool['eightSecTimer_Id']['state'] = TIMER_IDLE
timerPool['eightSecTimer_Id']['start'] = 0
timerPool['eightSecTimer_Id']['duration'] = 0
timerPool['eightSecTimer_Id']['time'] = 0

"""

"""
timerPool['fiveSecTimer_Id'] = {}
timerPool['fiveSecTimer_Id']['state'] = TIMER_IDLE

    timerPool[Id]
    if (timerPool[Id]['state'] == TIMER_IDLE) or (timerPool[Id]['state'] == TIMER_STOPPED):
        timerPool[Id]['start'] = default_timer()
        timerPool[Id]['state'] = TIMER_RUNNING
    return timerPool[Id]['state']

"""

def GetTimerState(Id):
    time = timerPool[Id]['time']
    if timerPool[Id]['state'] == TIMER_RUNNING:
        timerPool[Id]['duration'] = default_timer() - timerPool[Id]['start']
    else:
        None
    if timerPool[Id]['state'] == TIMER_STOPPED:
        timerPool[Id]['state'] = TIMER_IDLE

    if  timerPool[Id]['duration'] >= time:
        timerPool[Id]['state'] = TIMER_STOPPED
        timerPool[Id]['duration'] = 0
    return timerPool[Id]['state'] 

"""
Below is how to use.
"""
StartTimer('fiveSecTimer_Id',5)
StartTimer('eightSecTimer_Id',8)

while True:
    if GetTimerState('fiveSecTimer_Id') == TIMER_STOPPED:
        print "5 sec Timer Stopped"
    if GetTimerState('eightSecTimer_Id') == TIMER_STOPPED:

    sleep (.5)
