python程序函数计时

1 time计时示例

import timestart_time = time.time()# 执行待计算运行时间的代码
for i in range(2):time.sleep(3)end_time = time.time()
run_time = end_time - start_timeprint("程序的运行时间为：", run_time, "秒")

2 datetime计时示例

import time
import datetimestart_time = datetime.datetime.now()# 执行待计算运行时间的代码
for i in range(2):time.sleep(3)end_time = datetime.datetime.now()
run_time = end_time - start_timeprint("程序的运行时间为：", run_time)
