蟒蛇）我如何计算mininute

Question

两个时间之间的区别我想它通过这种方式

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) 

，但有太多的概率，如PM和AM，也

我不能之间无法计算使用 - 与str。

我现在不知道该如何使用该模块，所以任何人都可以帮助我？ ：C 我花了超过12小时的这个，并试图找到谷歌的帮助，但 所有的样本都使用该模块...帮助我！

您应该使用datetime对象本：

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) 

样品输入：

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