mechanism. In fact, the Pyfunctionobject object of the inner nested function inner_func is stored in the local variable of the outer function, and the Func_closure field in Pyfunctionobject is a tuple object that stores pycellobject. When executing Inner_func, the Pycellobject object stored in Func_closure is copied to the Pyframeobject free object of Inner_func, which is the storage space behind the cell object, so that the inner _func is referenced
