python計算時間差

前言

之前寫代碼都是看打印的初始和結束時間然后自己算間隔時間,感覺總是不方便,這不符合python的優雅簡潔,於是去尋找簡便之道.

方法

time模塊計算時間差

import time

s_time = time.time()
for i in range(1000):
    print(i)
c_time = time.time()
ss_time = c_time - s_time
print('%.3f秒'%ss_time)
print('執行結束！！！')

datetime時間模塊計算時間差

from datetime import datetime
a = datetime.now()
for x in range(10000):
    print(x)
b = datetime.now()
print(a)
print(b)
print("運行時間："+str(b-a)+" 秒")

from datetime import datetime
a = datetime.now()
for x in range(100000):
    print(x)
b = datetime.now()
print(a)
print(b)
print("運行時間："+str((b-a).seconds)+" 秒")

from datetime import datetime
a = datetime(2020, 10, 28, 14, 41, 9, 386637)
b = datetime(2020, 11, 29, 14, 41, 9, 386637)
print(a)
print(b)
print("運行時間："+str((b-a).days)+" 天")
