I wanted to format this string but I don't know how I can do the formatting part at all.

``````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 increment(self, t):
totalsec = self.get_sec() + t

def between(t1, t3, t2):
return t1.get_sec() <= t3.get_sec() <= t2.get_sec()

t1 = MyTime(9, 59, 59)

t2 = MyTime(10, 0, 1)

t3 = MyTime(10, 0, 0)

print (t1.increment(300))
print (t1.increment(-300))
``````

I want to format it with something like this:

``````"{:02d}:{:02d}:{:02d}".\
format(self.hours, self.minutes, self.seconds
``````

Any help would be great.

If you do `print(t1)`, you'll use the `__str__` method that you defined. The reason that it's not being called when you do `print(t1.increment(300))` is that `increment` returns an integer, not a `MyTime`, so `print` prints it using the normal rules for printing integers. To fix this you should probably make `increment` return a `MyTime` rather than an integer.

So I've changed increment as per your suggestion:

``````def increment(self, t):
totalsec = self.get_sec() + t
return MyTime(totalsec)
``````

But that adds t as hours, not as seconds.

Yes, because `secs` is the third argument and `hrs` is the first. You can use either `MyTime(0, 0, totalsec)` or `MyTime(secs = totalsec)`.
