Pointers in PYTHON?

 Memory programming is used in programming. A memory area is defined by: - associated variable name, - length as number of bytes, - address of the first byte, - content as a string of bits with contextual interpretation. The contents of the pointer variable are the address of a memory area. A variable is referred to when its address is loaded into a pointer variable. A pointer variable is redirected using its contents to reach the contents of the variable whose address it contains. The reference operator initializes the pointer variable. The pointer referral operator provides the contents of the memory area whose address it contains. And the PYTHON language natural works with pointer variables. PYTHON works differently and spectacular with pointers. (March 31, 2022)
