Answer 1

#Like this : Lenoname

ownerlist = []
petlist = []

class hamster :
def __init__ (self, typeofpet, name, gender, age) :

self.typeofpet = typeofpet
self.name = name
self.gender= gender
self.age = age

def __str__(self) :
return f" {self.typeofpet}, {self.name}, {self.gender}, {self.age}"

class owner :
def __init__ (self, name, lastname, pets) :
self.name = name
self.lastname = lastname
self.pets = pets

def __str__(self) :
return f"{self.name}, {self.lastname},{self.pets}"

pet1 = hamster('hamster', 'pell', 'male', 2)
petlist.append(pet1)

owner1 = owner('p1', 'son', petlist[0])
ownerlist.append(owner1)

for a in ownerlist:
print(a)

Answer 2

__str__ should return a str not print a str
So you can just write print(a) in your for loop.
And you give onwer1 1 pet not the complete list.
But in your onwer class you act with your for loop like that you expect a list.

Answer 3

Depends on what you want.
If you want use petlist[0] you could change your owner class.
Or you could write something like this.
[petlist[0]]
so you have a list.

Answer 4

Lenoname , sorry, why didn't you create a superclass from which to derive the subclasses of each animal (hamster, cat etc.)?
I don't say you are wrong or there is something wrong in your code...
Just to be simpler...
