The syntax of delattr () function in Python

Parameters of delattr function ()

The delattr () function in Python Picture 1

Delattr () has two parameters:

1. object: object name containing the deleted property.
2. name: The name of the attribute you want to delete from the object.

Value returned from delattr ()

Delattr () does not return any value. It only removes an attribute (if the object allows).

Example 1: How does the delattr () function work?

 class Toado: 
 x = 10 
 y = -5 
 z = 0   

 point1 = Toado()   

 print('x = ',point1.x) 
 print('y = ',point1.y) 
 print('z = ',point1.z) 
 
 delattr(Toado, 'z') 
  
 print('--Sau khi xoa thuoc tinh z--') 
 print('x = ',point1.x) 
 print('y = ',point1.y) 

Run the program, the result is:

 x = 10 
 y = -5 
 z = 0 
 --Sau khi xoa thuoc tinh z-- 
 x = 10 
 y = -5 

In this example, the attribute z is removed from the Toado class using the delattr function (Toado, 'z').

Example 2: Delete the attribute using the del operator .

In addition to using delattr, you can also remove the properties of an object using the del operator .

 class Toado: 
 x = 10 
 y = -5 
 z = 0 
 
 point1 = Toado() 
  
 print('x = ',point1.x) 
 print('y = ',point1.y) 
 print('z = ',point1.z) 
  
 # Xoa bo thuoc tinh z 
 del Toado.z 
  
 print('--Sau khi xoa thuoc tinh z--') 
 print('x = ',point1.x) 
 print('y = ',point1.y) 

Run the program, we get the same return result as example 1.
