So I've now gotten this: class MyTime: def __init__(self, hrs=0, mins=0, secs=0): self.hours = hrs self.minutes = mins self.seconds = secs if self.seconds >= 60: self.minutes += self.seconds // 60 self.seconds = self.seconds % 60 if self.minutes >= 60: self.hours += self.minutes // 60 self.minutes = self.minutes % 60 if self.hours >= 24: self.hours = self.hours % 24 def get_sec(self): return (self.hours * 60 + self.minutes) * 60 + self.seconds def __str__(self): return "{:02d}:{:02d}:{:02d}".\ format(self.hours, self.minutes, self.seconds) def between(self, t1, t2): return (t1.hours, t1.minutes, t1.seconds) <= (self.hours, self.minutes, self.seconds) and (self.hours, self.minutes, self.seconds) <= (t2.hours, t2.minutes, t2.seconds) t1 = MyTime(9, 59, 59) print("t1 =", t1) t2 = MyTime(10, 0, 1) print("t2 =", t2) t3 = MyTime(10, 0, 0) print("t3 =", t3) print("between(t2, t3, t1) =", between(t2, t3, t1)) print("between(t1, t3, t2) =", between(t1, t3, t2)) print("between(t3, t1, t2) =", between(t3, t1, t2)) print("between(t1, t2, t3) =", between(t1, t2, t3)) Am I on the right track or?
