What are the main components of the Python memory manager?

The main components of the Python memory manager are as follows:

  • The raw memory allocator handles the allocation of memory at a low level by interacting with the memory manager of the operating system.
  • Object-specific memory allocators interact with the private heap of objects and values in Python. These allocators execute memory operations that are specific to given data and object types.
  • The system allocators from the standard C library are responsible for helping the raw memory allocator interact with the memory manager of the operating system.

How does the Python memory model resemble a labeled directed graph?

The memory model keeps track of its data and variables via nothing but pointers: the value of every variable is a pointer, and this point can be pointing to a symbol, a number, or a subroutine. So...
