你可以测量 "wall time" (real world time), 或是"进程时间" (消耗的 CPU 时间). ===Example 1-85. 使用time 模块评价算法===[eg-1-85] ``` File: time-example-5.py import time def procedure(): time.sleep(2.5) # measure process time t0 = time.clock() procedure() print time.clock...
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: fromtimeitimportdefault_timerastimerdeftimer_func(func):defwrapper(*args,*...

current_utc_time = time.gmtime() print(f"Current UTC time: {current_utc_time}") Copy Developers can also create a more user-friendly date and time using thestrftimetime function. We will discuss this function in a later section.
