Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully. >>> sugar. tricks []

Following are the method to this question:

def __init__(self, _name, _breed):#defining Constructor

       """ Constructor """

       self.name = _name#assigning value in name variable

       self.breed = _breed#assigning value in breed variable

       self.tricks = []#defining tricks an empty list

Explanation:

In the above code, a parameterized constructor is defined, that hold two-variable "name and breed" in its parameter, and another object self is created for storing the value.

Inside the constructor two-variable, and one empty list variable "tricks" is defined that hold value in the name and breed variable, and the next step an empty list is defined, that store its value.
