和秒,能够进行加、减、比较等基本操作。你能够给我一个代码示例吗?
当然可以,下面是一个简单的实现:
```
class Time:
def __init__(self, hour=0, minute=0, second=0):
self.hour = hour
self.minute = minute
self.second = second
def __repr__(self):
return f"{self.hour:02}:{self.minute:02}:{self.second:02}"
def __add__(self, other):
total_seconds = self.second + other.second + \
(self.minute + other.minute) * 60 + \
(self.hour + other.hour) * 3600
return Time(total_seconds // 3600 % 24, total_seconds // 60 % 60, total_seconds % 60)
def __sub__(self, other):
total_seconds = self.second - other.second + \
(self.minute - other.minute) * 60 + \
(self.hour - other.hour) * 3600
return Time(total_seconds // 3600 % 24, total_seconds // 60 % 60, total_seconds % 60)
def __eq__(self, other):
return self.hour == other.hour and self.minute == other.minute and self.second == other.second
def __lt__(self, other):
return (self.hour, self.minute, self.second) < (other.hour, other.minute, other.second)
def __gt__(self, other):
return (self.hour, self.minute, self.second) > (other.hour, other.minute, other.second)
def __le__(self, other):
return (self.hour, self.minute, self.second) <= (other.hour, other.minute, other.second)
def __ge__(self, other):
return (self.hour, self.minute, self.second) >= (other.hour, other.minute, other.second)
```
在这个示例中,我们实现了 __init__ 方法初始化时分秒,__repr__ 方法将时间对象转化为字符串,这是方便输出。__add__ 和 __sub__ 方法分别实现了时间相加和相减,我们将两个时间对象中的时分秒分别相加或相减,得到新的时分秒,并在最后返回一个新的时间对象。__eq__、__lt__、 __gt__、__le__ 和 __ge__ 方法实现了比较运算符的操作,用于在时间对象之间进行比较。
