vars()

class Animal():
    #instance attributes
    def __init__(self1,name1,age):
        self1.name= name1
        self1.age=age

#instantiate the Animal  class
tiger=Animal("Ronald",5)  # tiger is an object of Animal class

print(vars(tiger)) # {'name': 'Ronald', 'age': 5}

{'name': 'Ronald', 'age': 5}

id=5
print(vars(id))

TypeError                Traceback (most recent call last)
 in 
      1 id=5
----> 2 print(vars(id))

TypeError: vars() argument must have __dict__ attribute

Example 1: Using vars() Without Arguments

x = 10
y = "example"
print(vars())  # Output: current local variables

{'x': 10, 'y': 'example'}

Example 2: Using vars() on a Custom Class

class SimpleClass:
    def __init__(self, name):
        self.name = name
obj = SimpleClass("test")
print(vars(obj))  # Output: {'name': 'test'}

{'name': 'test'}

Example 3: Using vars() on Built-in Types

my_list = [1, 2, 3]
try:
    print(vars(my_list))
except TypeError as e:
    print(f"Error: {e}")

Error: vars() argument must have __dict__ attribute

Example 4: Modifying Object Attributes with vars()

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

p = Person("Alice")
vars(p)['name'] = "Bob"
print(p.name)  # Output: Bob

Bob
