2. How to make a copy constructor?
Since Python lacks overloading based on parameter types, generally one
does it the other way around and instead provides a method that
produces a copy of the object. For example:
class Point(object):
def __init__(self, x, y):
self. x = x
self.y = y
def copy(self):
return Point(self.x, self.y)
For simple enough cases, the copy and deepcopy functions in the copy
module are just fine:
