Python vars()

The syntax of the vars() function is :

vars(object)

vars() parameters

vars() function takes only one parameter as argument:

• object - Any object having the __dict__ attribute or module,class ,instance.

Example 1: How to use vars() function on python?

class Dog:
  def __init__(self, a = 4, b = 8):
    self.a = a
    self.b = b
  
object = Dog()
print(vars(object))

{'a': 4, 'b': 8}

The __dict__ attribute is a dictionary containing the specific object’s changeable attributes.

Rules of vars()

• If called without any parameters, it will return a dictionary containing the local symbol table.
• vars() will return the __dict__ attributes of the given object.
• If the object passed to vars() doesn’t have the __dict__ attribute, it raises a TypeError exception.
