Python: generator expression vs. yield http://stackoverflow.com/questions/1995418/python-generator-expression-vs-yield three extra instructions in the setup but from the first FOR_ITER they differ in only one respect the yield approach uses a LOAD_FAST.. xrange 6 LOAD_FAST 0 x 9 CALL_FUNCTION 1 12 GET_ITER 13 FOR_ITER 40 to 56 16 STORE_FAST 2 i 3 19 SETUP_LOOP 31 to 53 22 LOAD_GLOBAL.. xrange 25 LOAD_FAST 1 y 28 CALL_FUNCTION 1 31 GET_ITER 32 FOR_ITER 17 to 52 35 STORE_FAST 3 j 4 38 LOAD_FAST 2 i 41 LOAD_FAST 3..
Why is looping over range() in Python faster than using a while loop? http://stackoverflow.com/questions/869229/why-is-looping-over-range-in-python-faster-than-using-a-while-loop 9 LOAD_CONST 1 100000000 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..
