Why are you calling time as a function, when it is a tijd instance?

Hello Steve,
I found this in my tutorial.
13.8. Instances as return values¶
Functions can return instances. For example, find_center takes a Rectangle as
an argument and returns a Point that contains the coordinates of the center of
the Rectangle:
def find_center(box):
p =oint()
p.x =ox.corner.x + box.width/2.0
p.y =ox.corner.y - box.height/2.0
return p
To call this function, pass box as an argument and assign the result to a
variable:
center =ind_center(box)
print_point(center)
(50.0, 100.0)
So i followed it but appearently not the good way.

There's a big difference between print_point() and print time().
print_point() in your tutorial is a function, presumably defined
someplace else.
You used print time(), (no underscore), which uses the print statement,
and tries to call a function called time().
Since you defined time as an instance of your class, and didn't do
anything special, it's not callable.
