\"\"<\/p>\n

Memory allocation is the process of allocating memory to a computer program. In Python, the process of memory allocation and deallocation is handled automatically as there is a garbage collector which is created in python so that users don\u2019t have to handle the process of garbage collection. <\/p>\n

Garbage Collection<\/h3>\n

It is a process in which memory is deallocated when it is not in use to make the space available for other objects. In case, when no one is referencing the object in memory then in the virtual machine, the garbage collector comes to work to automatically delete the object in the heap memory.<\/p>\n

Reference Counting<\/h3>\n

It is a procedure that works by counting the number of times an object is referenced by other objects in the computer. This count for an object is decremented when reference to an object is removed. And when this count becomes zero, then that object is deallocated.
\nFor example, in the case of two variables having the same value. Then the virtual machine instead of making two different objects, it makes two pointers pointing at the same object created in the private heap.<\/p>\n
