Python Classes - Memory Allocation and Garbage Collection

Memory allocation is the process of granting and allocating memory when an application requests it.

The python runtime automatically allocates memory for your objects, such as lists, dictionaries, etc. It does this by requesting memory from your operating system. An application cannot use memory that is not allocated.

In some programming languages, like C++, the programmer is responsible for memory allocation. However, with Python, all the memory allocation is done by the Python runtime, which makes things easier.

Garbage collection is the process of deallocating memory in an application

A reference count is an integer that counts the number of times a variable is referencing an object, and the garbage collector deallocates the object if that reference count = 0

Note that the time an object is deallocated after the reference count becomes 0 may differ across different Python runtime implementations.
