1 time计时示例

复制代码

import time

start_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_time

print("程序的运行时间为：", run_time, "秒")

2 datetime计时示例

复制代码

import time
import datetime

start_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_time

print("程序的运行时间为：", run_time)
