How can you access the attributes of an object declared in a class in Python?

In Python, access to the attributes of an object declared in a class is done through dot notation. For example:

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

p = Person('Ivan', 30)
print(p.name)  # Outputs: Ivan
print(p.age)   # Outputs: 30

Here, p.name and p.age are accesses to the attributes of the object p. You can also use the functions getattr() and setattr() for dynamic access:

print(getattr(p, 'name'))  # Ivan
setattr(p, 'age', 31)
print(p.age)  # 31
