Python vars
Python vars() builtin function is used to get the __dict__ attribute of the given object.
In this tutorial, we will learn about the syntax of Python vars() function, and learn how to use this function with the help of examples.
Syntax
The syntax of vars() function is
vars([object])
where
| Parameter | Required/Optional | Description |
|---|---|---|
| object | Required | A Python object with a __dict__ attribute. |
Returns
The function returns a dictionary.
Examples
1 Get dict attribute for Class
In this example, we define a class, and get the __dict__ attribute of this class.
Python Program
class A:
name = 'Apple'
count = 25
result = vars(A)
print(result)
Output
{'__module__': '__main__', 'name': 'Apple', 'count': 25, '__dict__': <attribute '__dict__' of 'A' objects>, '__weakref__': <attribute '__weakref__' of 'A' objects>, '__doc__': None}
2 Get dict attribute for a List
In this example, we try to get the __dict__ attribute of a list object. Since a list does not contain a __dict__ attribute, interpreter would raise TypeError.
Python Program
x = ['apple', 'banana'] result = vars(x) print(result)
Output
Traceback (most recent call last):
File "/Users/tutorialkart/Desktop/Projects/PythonTutorial/Example.py", line 2, in <module>
result = vars(x)
TypeError: vars() argument must have __dict__ attribute
Conclusion
In this Python Tutorial, we have learnt the syntax of Python vars() builtin function, and also learned how to use this function, with the help of Python example programs.
