Passing multiple strings to a function and appending to list

Question

class Dog:
   tricks = []
   def __init__(self,name):
     self.name=name
   def add_tricks(self, trick ):
     self.tricks.extend(trick)

I keep getting the error that add_tricks only accepts 1 positional arguments but 3 were given. I tried passing **kwargs to the function but that didn't work either. How do I pass multiple strings to the function?

For (*args) parameters as ("Hello","Byy")

class Dog:
   tricks = []
   def __init__(self,name):
     self.name=name
   def add_tricks(self, *trick):
     self.tricks.extend(trick)

For (**kwargs) parameters as (a="Hello",b="Byy")

class Dog:
   tricks = []
   def __init__(self,name):
     self.name=name
   def add_tricks(self, **trick):
     self.tricks.extend(trick.values())

Or if you want to give string in both types like ("Hello",b="byy")

class Dog:
   tricks = []
   def __init__(self,name):
     self.name=name
   def add_tricks(self, *trick1,**trick2):
     self.tricks.extend(trick)
     self.tricks.extend(trick2)

So it works when I use the *args method but produces errors using **kwargs like in your second code. "add_tricks() takes 1 positional argument but 3 were given"

a = Dog("bruno") a.add_tricks("fetch", "roll") This is what I am trying to add
