Destructor in python

What are Destructor in python ? 

Destructor  is called when an object gets destroyed. In Python, destructors are not needed, because Python has a garbage collector that handles memory management automatically. 

The __del__() method is known as a destructor method.  

Example:

  • class ClassName:
    • def __del__(self):
destructor in python

Function of Destructor in Python:

  • The __del__ method is similar to destructor in c++ and Java.
  • Destructors are used to destroying the object’s state.

Syntax:

class ClassName:
def __del__( self ,):
##body

Code #1 for Destructor in Python:

#python Program
#Rishikesh 
#destructor
 
class A(object): 
    def __init__(self): 
        self.str1 = “PrepInsta”
        print(“Object Created” , self.str1) 
    def __del__(self):
        print(‘DEstructor is called automatically’)
        

 

ob = A() 

Output: 

Object Created PrepInsta
DEstructor is called automatically
  • The destructor was called after the program ended.
  • It was called Automatically.
  • Object will be deleted at the end of the program.

Code #2 :


#python Program
#Rishikesh 
#destructor
 
class A(object): 
    def __init__(self): 
        self.str1 = “PrepInsta”
        print(“Object Created” , self.str1) 
    def __del__(self):
        print(‘DEstructor is called Manually’)
        

ob = A() 
del ob 
#ob1=A()
#destructor will be called automattically for ob1 

Output: 

Object Created PrepInsta
DEstructor is called Manually
