Question

我正在开发一个需要两个输入的程序。第一个是时间（24小时制），如12:30或14:00，第二个输入是经过的时间（以分钟为单位），如30或90（因此显示1:00或15:30）

我的主要问题是我有很多if / else语句，而且我认为我可能效率很低。我希望有人可以帮我弄清楚我需要考虑的所有特殊情况。如果您给出不会使小时更改两次的数字，该程序目前有效。我真的可以使用一些帮助来提高效率。我在代码中尽可能地评论，以帮助您理解我对每行代码的意图。

代码：

# Taking User Input
startTime = input()
duration = int(input())

# Splitting up the hour and minutes by the colon
rawTime = startTime.split(':')

# Assigning the hour and the minute variables
hourHand = int(rawTime[0])
minuteHand = int(rawTime[1])

# Giving the remainder when you add the minutes and the duration (so 
# if it goes over 60 you know by how much) 
newMinuteHand = (minuteHand+duration)%60

# Checking to see if newMinuteHand is greater than 0, meaning it goes 
# into the next hour.
# Also checking to make sure the hour is not 23:00 or close to 
# midnight because that carries over
# to 0:00
if newMinuteHand >= 0 and hourHand != 23:
   newHourHand = hourHand + 1
   # A couple statements needed here to correctly format the minute 
   # side.
    if newMinuteHand >= 10:
    newTime = str(newHourHand) + ':' + str(newMinuteHand) 
    print(newTime)
   else:
      newTime = str(newHourHand) + ':0' + str(newMinuteHand)
      print(newTime)

# Checking for the case that the hour is 23:00
elif newMinuteHand >= 0 and hourHand == 23:
   newHourHand = 0

   if newMinuteHand >= 10:
    newTime = str(newHourHand) + '0:' + str(newMinuteHand) 
    print(newTime)
   else:
      newTime = str(newHourHand) + '0:0' + str(newMinuteHand)
      print(newTime)

Answer 1

你应该可以这样：

hourHand = 23
minuteHand = 00
duration = 61

total_minutes = minuteHand + duration
additional_hours = int(total_minutes / 60)
final_minutes = total_minutes % 60
final_hours = (hourHand + additional_hours) % 24

final_time = "{0}:{1}".format(final_hours,str(final_minutes).rjust(2,"0"))

print(final_time)

但是你还没有明确指出你的输入和输出足以让我知道。

在分钟上使用rjust（2，“0”）可以防止你使用if blah＆lt;的if语句10或者你在做什么。

其他一切都应该由除法和模数运算符来处理。

将两行输入作为时间和经过的持续时间，显示新时间
