time 模块 1、测量执行时间:时间模块通常用于度量代码段的执行时间。这在优化代码或比较不同算法的性能时特别有用。import timestart_time = time.time()# Code snippet to measure execution timeend_time = time.time()execution_time = end_time - start_timeprint("Execution Time:", execution_time, "...
Use a decorator to measure the time of a function¶ If you want to measure the time for multiple parts in your code and don't want to repeat the above code snippets every time, you can write a decorator that simply wraps the function and measures the execution time: ...
Write a Python function that executes a list of asynchronous tasks concurrently with asyncio.gather, then returns a list of results along with the total elapsed time. Write a Python program to implement a set of concurrent tasks with asyncio.gather(), measure the time taken for execution, and...
