英文:
Is there a function to see how long a script takes to run?
问题
我有一个可以对文件进行排序的Python脚本，我想知道它运行需要多长时间。
我搜索了一个名为"time"的模块，但它不起作用，并要求我提供实际时间。

你可以像这样计算执行时间：
import timestart_time = time.time()# 在这里放入你的脚本end_time = time.time()execution_time = end_time - start_timeprint("执行时间：", execution_time, "秒")
英文:
You can calculate execution time like that:
import timestart_time = time.time()# your script hereend_time = time.time()execution_time = end_time - start_timeprint("Execution time:", execution_time, "seconds")

I prefer to use time.perf_counter() if we are talking about timing code:
from time import perf_counter# 获取开始时间t1 = perf_counter()# 一些复杂耗时的函数for i in range(10**9):pass# 获取结束时间t2 = perf_counter()# 现在你可以从结束时间减去开始时间，得到经过的时间：print("经过的时间：", t2 - t1)

英文:
I prefer to use time.perf_counter() if we are talking about timing code:
from time import perf_counter# Get the start 'time't1 = perf_counter()# Some complex time-consuming functionfor i in range(10**9):pass# Get the end 'time't2 = perf_counter()# Now you subtract the start time from the end time and you have your elapsed time:print("Elapsed time:",t2-t1)
