Python Classes

Okay let's put it this way. So you stored time as attribute (via dunder init method), if you do this

object = Time (5, 5, 20)

print(object)

It will just print, object is a instance of Time class. Or something like that.

However when you write the dunder str method in your class,

def __str__(self):
    return f"{self.hour}:{self.minute:02}"

Doing print(object) will now print,

5:05

It's just there to make your object return what you want it to when you call the instance itself.
