Destructors

Destructors are called when an object gets destroyed. In Python, destructors are not needed as much needed in C++ because Python has a garbage collector that handles memory management automatically. The __del__() method is a known as a destructor method in Python. It is called when all references to the object have been deleted i.e when an object is garbage collected.

Example 1:

# Python program to illustrate destructor 
class Employee: 

	# Initializing 
	def __init__(self): 
		print('Employee created.') 

	# Deleting (Calling destructor) 
	def __del__(self): 
		print('Destructor called, Employee deleted.') 

obj = Employee() 
del obj 

Employee created.

Destructor called, Employee deleted.

Example 2:

# Python program to illustrate destructor 

class Employee: 

	# Initializing 
	def __init__(self): 
		print('Employee created') 

	# Calling destructor 
	def __del__(self): 
		print("Destructor called") 

def Create_obj(): 
	print('Making Object...') 
	obj = Employee() 
	print('function end...') 
	return obj 

print('Calling Create_obj() function...') 
obj = Create_obj()
del obj 
print('Program End...') 

Calling Create_obj() function...

Making Object...

Employee created function end...

Destructor called

Program End...
