如何在分钟内计算两次之间的差异

Question

我这样尝试过

time1=input("Enter your first time (ex.xx:xxPM) : ")
am_or_pm1=time1[-2:].upper()
colpos1=time1[2:3]
hour1=time1[0:2]
minute1=time1[3:5]
print('This is your first time')
print(time1)

time2=input("Enter your first time (ex.xx:xxPM) : ")
am_or_pm2=time2[-2:].upper()
colpos2=time2[2:3]
hour2=time2[0:2]
minute2=time2[3:5]
print('This is your second time')
print(time2)

timediff=(time1 - time2)
print(timediff)

但是有太多的概率，例如无法在PM和AM之间进行计算，并且

我不能使用-与STR。

我现在不知道如何使用该模块，因此任何人都可以帮助我？ ：CI为此花费了超过12个小时的时间，并试图在Google上找到帮助，但是所有示例都在使用该模块...帮助我！

Answer 1

您应该为此使用datetime对象：

from datetime import datetime

time1=input("Enter your first time (ex.xx:xxPM) : ")
timeObj1 = datetime.strptime(time1,'%I:%M%p')

time2=input("Enter your first time (ex.xx:xxPM) : ")
timeObj2 = datetime.strptime(time2,'%I:%M%p')

print(timeObj1-timeObj2)

输入样例：

Enter your first time (ex.xx:xxPM) : 5:30PM
Enter your first time (ex.xx:xxPM) : 5:00PM
0:30:00
