我有这个代码:
for times in range(50): factor = (min(getHeight(),getWidth()) / math.sqrt(qtdPosicoes)) * guess() positionInGrid = {} grid = np.zeros((getGridColumns(),getGridLines())) groupMatrix = np.zeros((grid.shape[0], grid.shape[1])) groups = getGroups(grid, listaComPosicoes, getXRanges(listaComPosicoes),getYRanges(listaComPosicoes)) solution = calculaSilhueta() if bestSolution is None or solution > bestSolution: bestSolution = solution
我在文档时间模块中找到了但我不明白如何使用
使用此模块的一种简单方法是time.time()
标记代码的开头,然后time.time()
再次使用以标记代码的结尾.之后,减去它们以便获得持续时间.
所以你的代码应该像:
for times in range(50): start = time.time() #do some stuff stop = time.time() duration = stop-start print(duration)
例:
>>> for i in range(3): start = time.time() print(i) stop = time.time() print(stop-start) 0 0.08444404602050781 1 0.014003992080688477 2 0.009001970291137695
但更好的选择是使用timeit
模块,这更容易:
>>> import timeit >>> def myfunction(time): print(time) >>> result = timeit.timeit("for i in range(2): myfunction(i)", setup="from __main__ import myfunction", number=1) 0 1 >>> result 0.0868431608504352
希望这可以帮助!
