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...

for method in methods: elapsed_time = measure_time(method, original_string) print(f"{method.__name__}: {elapsed_time:.6f} seconds") 通过以上代码可以对几种方法的性能进行测试,结果可能因字符串长度和具体实现细节而异。 七、总结 Python 提供了多种方法来实现字符串反转,包括切片、循环、内置函数、...

print(time.time() - now) # 2.0025689601898193 print(asyncio.sleep(1)) # <coroutine object sleep at 0x102f663b0> coro = async_hello_world() asyncio.run(coro) 由此我们可以看到,asyncio.sleep(1)是一个coroutine object,对它进行await就会使得当前coroutine休眠一秒。
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...
