9 CALL_FUNCTION 1 12 GET_ITER 13 FOR_ITER 6 to 22 16 STORE_NAME 1 i 2 19 JUMP_ABSOLUTE 13 22 POP_BLOCK 23 LOAD_CONST 2 None.. The difference is that STORE_FAST is faster than STORE_NAME . This is because in a function i is a local but at toplevel..

a more concrete idea use while loop 1 0 LOAD_CONST 0 0 3 STORE_NAME 0 i 2 6 SETUP_LOOP 28 to 37 9 LOAD_NAME 0 i # 12 LOAD_CONST.. LOAD_NAME 0 i # 25 LOAD_CONST 2 1 # 28 INPLACE_ADD # 29 STORE_NAME 0 i # 32 JUMP_ABSOLUTE 9 # 35 POP_TOP 36 POP_BLOCK The loop.. 12 CALL_FUNCTION 2 15 GET_ITER 16 FOR_ITER 6 to 25 # 19 STORE_NAME 1 n # 2 22 JUMP_ABSOLUTE 16 # 25 POP_BLOCK 26 LOAD_CONST 2 None..
