I tested few cases (all positive, all negative, mixed), and did not found any performance difference after this change. ./python -m perf timeit -s "a = list(range(10**4))" -- "sum(a)" ./python -m perf timeit -s "a = [-i for i in range(10**4)]" -- "sum(a)" ./python -m perf timeit -s "a = [i*(-1)**i for i in range(10**4)]" -- "sum(a)" |
