def code_to_measure(): # 这里放置需要测量时间的代码 pass 使用timeit测量平均运行时间 elapsed_time = timeit.timeit(code_to_measure, number=1000) print(f"代码平均运行时间: {elapsed_time} 秒") 使用cProfile进行详细性能分析 cProfile.run('code_to_measure()') 通过结合使用timeit和cProfile,我们可以...
Usetime.time()¶ You can usetime.time()to create the current time. Then you determine the time before and after the code part you want to measure, and in the end you can subtract the time points to get the elapsed time: importtimestart=time.time()# your code...end=time.time()pr...
elapsed_time = end_time - start_time print(f"Elapsed time with sleep: {elapsed_time} seconds") 二、使用DATETIME模块记录时间间隔 datetime模块提供了更高层次的日期和时间操作。相比于time模块,datetime模块更加直观,适合处理更复杂的时间操作。 1、获取当前时间 首先,使用datetime.now()方法获取当前时间: fro...

default_timer 函数:default_timer函数返回默认的计时器,通常是time.perf_counter或time.process_time。这在需要跨平台支持的时候特别有用。示例代码如下: import timeitimport timestart_time = timeit.default_timer()# Code snippet to measure execution timeelapsed = timeit.default_timer() - start_timeprint(f...

TimeRun is a simple, yet elegant elapsed time measurement library for Python. It is distributed as a single file module and has no dependencies other than the Python Standard Library.Elapsed Time: Customized time delta which represents elapsed time in nanoseconds. Stopwatch: An elapsed time ...
start_time = time.time # code to measure sum(range(100)) end_time = time.time elapsed_time = end_time - start_time print(f'Execution time: {elapsed_time:.2f} seconds') 注意:这些方法只会测量单元格中代码的执行时间。如果计算单元依赖于其他计算单元或外部资源,则执行时间将不包括执行这些依赖...
